COLUMBUS, Ohio --Seven of eight relatives who were killed in their southern Ohio homes Friday had been shot multiple times, including one who was shot nine times, according to autopsy results released Tuesday. 
 
 Some also had bruising, which matched a report from a 911 caller who said two appeared to have been beaten up. 
 
 The Hamilton County coroner said the victims - three women, four men and a 16-year-old boy - had wounds to their heads, torso and other parts of the body. Dr. Lakshmi Sammarco's report said one victim had a single wound, one had two wounds, and the rest had three or more. The report didn't specify which victim had which number of wounds. 
 
 Ohio's attorney general has called the deaths carefully planned slayings carried out at four locations in Piketon, a rural Appalachian Mountain region community. Mike DeWine has also said there were marijuana growing operations at three of the locations where bodies were found. 
 
 Investigators are also looking at the possibility a Mexican drug cartel is behind the pre-planned execution of the family. 
 
 A law enforcement source confirmed to CBS News that investigators found some 200 marijuana plants. They were inside an indoor grow operation that was found in some of the homes where the eight members of the Rhoden family were executed. 
 
 The size of the operation, according to the source, indicates the marijuana was being grown for sale and not for personal use. 
 
 "There is a drug problem in most areas around here," said Pike County Sheriff Charles Reader. 
 
 Law enforcement sources estimate that the street value of the marijuana plants is nearly half a million dollars. 
 
 But Ohio Attorney General Mike DeWine, who is heading up the investigation, couldn't say with certainty whether that may have been a factor in the murders. 
 
 "We have no idea. I mean you know we're running those leads out, there's many different theories," DeWine said. 
 
 DeWine said Tuesday that investigators have received more than 300 tips and are continuing to serve search warrants in an effort to identify the killer or killers. He said 79 pieces of evidence have been sent to a state crime lab for testing and analysis. 
 
 Authorities have said members of the Rhoden family were targeted in the slayings. 
 
 A woman who called 911 Friday morning to report finding two of the bodies said that she saw "blood all over the house" and that the two looked like they had been badly beaten. 
 
 The victims are 40-year-old Christopher Rhoden Sr.; his ex-wife, Dana Rhoden; their three children, 16-year-old Christopher Rhoden Jr., 19-year-old Hanna Rhoden and 20-year-old Clarence "Frankie" Rhoden; Christopher Rhoden Sr.'s brother, 44-year-old Kenneth Rhoden; their cousin, 38-year-old Gary Rhoden; and 20-year-old Hannah Gilley, whose 6-month old son with Frankie was unharmed. Two other children, a 6-month-old and a 3-year-old, were also unharmed. 
 
 Leonard Manley, father of Dana Rhoden, told the Cincinnati Enquirer that he first learned about the marijuana operations from news reports. Manley, 64, said he's sure his daughter couldn't have been involved in anything illegal. 
 
 "They are trying to drag my daughter through the mud, and I don't appreciate that," said Manley, whose three grandchildren - Dana's children - were also among the dead. 
 
 Manley also noted that the assailant was able to get by his daughter's two dogs. 
 
 "Whoever done it knows the family," Manley said. "There were two dogs there that would eat you up." 
 
 Pike County Prosecutor Rob Junk told the Columbus Dispatch on Monday that the marijuana operations included a grow house sheltering hundreds of plants. 
 
 "It wasn't just somebody sitting pots in the window," Junk said. 
 
 DeWine said Monday there was also possible evidence of cockfighting at one of the properties, but he didn't know what was relevant to the investigation. 
 
 More than a dozen counselors, clergy and psychologists arrived at the local high school on Monday to help friends and neighbors cope with their grief as they remembered the victims as loyal and caring people. 
 
 Dana Rhoden "always wanted what was best for her kids," Scioto Valley Local School District Superintendent Todd Burkitt said. 
 
 The youngest victim, Christopher Rhoden Jr., was a freshman at Piketon High School. 
 
 "He was the first one that if he thought that someone wasn't being treated fairly or felt like someone wasn't being treated appropriately, he would speak up about it," Burkitt said. 
 
 Hanna and Frankie Rhoden also had attended the school. 
 
 While authorities have not released any details about a motive, the attorney general's office did confirm Monday that one of the victims had received a threat via Facebook. Authorities didn't elaborate.

 While investigators in Ohio struggled for a fifth day to find a motive and the person or people responsible for the massacre of eight members of the same family, officials said Tuesday that autopsy results revealed that some of the victims show signs of struggle before they were killed. 
 
 The Pike County Medical Examiner said the eight victims — all part of the Rhoden family — died from gunshot wounds. One victim suffered nine gunshot wounds, and some victims showed soft tissue bruising, indicating that they fought their killer or killers, according to the medical examiner. 
 
 Hannah Gilley, 20; Christopher Rhoden, Sr., 40; Christopher Rhoden, Jr., 16; Clarence "Frankie" Rhoden, 20; Dana Rhoden, 37; Gary Rhoden, 38; Hanna Rhoden, 19; and Kenneth Rhoden, 44, of Piketon, were found dead Friday across four Pike County crime scenes. 
 
 A 4-day-old, a 6-month-old and a 3-year-old survived the massacre, which authorities have described as "execution-style" and "pre-planned."

 Ohio Attorney General Mike DeWine and Pike County Sheriff Charles Reader said Tuesday that investigators were looking at about 80 pieces of evidence and had received more than 300 tips, but did not say whether they have identified a suspect or suspects. 
 
 On Sunday, DeWine said three separate marijuana "grow operations" were found during the searches of the crime scenes. Officials told NBC News on Tuesday that one of the grow operations was comprised of more than 100 marijuana plants, and the drugs were not for personal use by the grower. 
 
 DeWine and Reader said Sunday that the county and the state as a whole have a "drug problem." A 2011 report said that the drug trafficking threat in Ohio was on the rise. More than $6 million in marijuana was seized last year, and more than 550 plants were seized from Pike County. Some Ohio counties saw less than 10 plants seized, while some had thousands seized last year. 
 
 DeWine also said that birds in small cages were found at some of the crime scenes, which might indicate cockfighting was taking place, but the discovery was still under investigation. ||||| The execution-style murders of eight members of the same family in rural Pike County, Ohio, has set residents on edge and sent investigators into overdrive as they try to find out who killed the Rhoden family members, and why. 
 
 Adding to the intrigue: the discovery of marijuana growing operations at three of the four crime scenes. 
 
 Here's what we know, and don't know, about the crimes: 
 
 The killings 
 
 What we know: 
 
 In a series of what investigators called well-planned, execution-style killings carried out at four locations, eight members of a single family were methodically shot in the head Friday while they slept in their homes about 50 miles south of Columbus. 
 
 A relative discovered the bodies. 
 
 "There's blood all over the house," the woman told 911 operators. "My brother-in-law is in the bedroom. It looks like they beat the hell out of him." 
 
 Authorities identified the victims as Hannah Gilley, 20; Christopher Rhoden Sr., 40; Christopher Rhoden Jr., 16; Clarence "Frankie" Rhoden, 20; Dana Rhoden, 37; Gary Rhoden, 38; Hanna Rhoden, 19; and Kenneth Rhoden, 44. 
 
 Authorities in Ohio released this chart tracing the relationships of the slain Rhoden family members. 
 
 Amid all the carnage, three children were found unharmed -- a 4-day-old infant who was next to her mother when she was killed, a 6-month-old baby and a 3-year-old. State authorities are now caring for the survivors. 
 
 Two of the residences where the killings took place are within walking distance, authorities said. A third is about a mile away and the fourth about eight miles away, they said. 
 
 What we don't know: 
 
 Who killed them, or why. Authorities do, however, think the killers were familiar with the victims. 
 
 "It was a sophisticated operation and those who carried it out were trying to do everything they could do to hinder the investigation and their prosecution," Ohio Attorney General Mike DeWine said.

 Marijuana grow operations found 
 
 What we know: 
 
 Extensive marijuana grow operations were found at three of the sites, DeWine told reporters Sunday. 
 
 An official with knowledge of the operation told CNN's Nick Valencia that the marijuana wasn't being grown for personal use. 
 
 An aerial view of one of the crime scenes. 
 
 "It was for something much bigger than that. It was a very sophisticated operation," the official said. 
 
 Such operations are often located indoors, and use elaborate lighting, watering and feeding systems designed to yield crops every three to four months, according to an April article in Police Chief magazine 
 
 What we don't know: 
 
 Whether the killings had anything to do with the marijuana grow operation. 
 
 The investigation 
 
 What we know: 
 
 It's likely to be lengthy. 
 
 DeWine said police have executed at least five search warrants and 50 of 60 people have been interviewed so far. Authorities have received 100 tips and 18 pieces of evidence have been submitted to the crime lab. Seven of the eight autopsies have been performed so far, he said. The last one scheduled is for Monday, said DeWine. 
 
 What we don't know: 
 
 What investigators have found or how many guns were used in the shootings. 
 
 Family warned 
 
 What we know: 
 
 Pike County Sheriff Charles Reader 
 
 Pike County Sheriff Charles Reader said he has cautioned surviving family members that they may still be in the killers' crosshairs. 
 
 "We have a specific family that's been targeted but I don't think there's been a threat to any other members of the community," he said. "I cautioned them they are a target and I cautioned them, 'Be armed.'" 
 
 What we don't know: 
 
 Exactly why the Rhoden family had been targeted -- or if it had anything to do with the marijuana operation. 
 
 Pot in Pike County 
 
 What we know: 
 
 Pike County is no stranger to marijuana problems. In August 2012, Ohio law enforcement officers found "a major marijuana grow site in Pike County with suspected ties to a Mexican drug cartel," according to a press release DeWine's office issued at the time. 
 
 Investigators destroyed about 1,200 marijuana plants and found two abandoned campsites they believe belonged to Mexican nationals, the release said. 
 
 What we don't know: 
 
 DeWine has not indicated any connection between the 2012 findings and the operations found on the Rhoden properties. ||||| Rumors swirling on the street far outnumbered any official information released Monday about last week's killing of eight members of one family in Pike County, yet the trickled-out details allowed a clearer picture of the Rhodens and the murder investigation now entering its fifth day. 
 
 PIKETON, Ohio - Rumors swirling on the street far outnumbered any official information released Monday about last week's killing of eight members of one family in Pike County, yet the trickled-out details allowed a clearer picture of the Rhodens and the murder investigation now entering its fifth day. 
 
 The Pike County prosecutor said for the first time that the marijuana operations discovered at three of the four Rhoden property crime scenes were far from a few illicit plants growing in somebody's backyard for recreational use. 
 
 Prosecutor Rob Junk said that one of the marijuana grow sites was indoors, and there were several hundred plants found. 
 
 "It wasn't just somebody sitting pots in the window," he said. 
 
 And the Ohio attorney general's office said that animals and structures on the property indicate that roosters were being bred there for cockfighting.

 Yet Junk said law-enforcement had been familiar with the Rhodens only for other reasons. "Altercations with people, that sort of thing," he said. "Nothing like this." 
 
 The dead who were found on Friday morning: Dana Rhoden, 37; Dana's ex-husband, Christopher Rhoden Sr., 40; their children, Christopher Rhoden Jr., 16, Hanna Rhoden, 19, and Clarence "Frankie" Rhoden, 20; Frankie's fiancee, Hannah Gilley, 20; Kenneth Rhoden, 44, who is Rhoden Sr.'s brother; and Gary Rhoden, 38, Rhoden Sr.'s cousin. 
 
 The law-enforcement response into the investigation remains massive. No one has been arrested, and officials have not said that they have any particular suspects in mind. 
 
 Also new on Monday, authorities said that all eight autopsies have been finished and that donations to help the family can be made through the Rhoden Memorial Fund at any Fifth Third Bank. No funeral arrangements have been announced. 
 
 The Ohio Bureau of Criminal Investigation, part of the Ohio attorney general's office, still has at least 35 special agents, crime-scene investigators and analysts in Piketon to assist Pike County Sheriff Charles Reader's office. 
 
 "This is unprecedented," Attorney General Mike DeWine said both of the ghastliness of the crime and the response to the investigation. "I don't know that in the history of the BCI that we've tackled anything of this magnitude." 
 
 In light of the drug operations, he said the FBI and the Drug Enforcement Administration are aware of the situation and have offered to help. 
 
 No one has officially offered a motive, but speculation is running rampant about how the marijuana signals some connection to a Mexican drug cartel. That is largely fueled by the fact that in 2012, BCI agents - during their annual hunt for marijuana plants - found 1,200 plants growing on a Pike County hillside. They also found abandoned camps with evidence that Mexican nationals had stayed there. At the time, DeWine said he suspected the work of a cartel. 
 
 Authorities have not publicly addressed such a connection with this investigation, but they have said the killings - with each victim shot in the head while sleeping - were sophisticated and well-planned and that the killers covered their tracks. 
 
 Todd Burkitt is superintendent of Scioto Valley schools, and he knew all of Dana and Christopher Rhoden's children because they had gone to school there; Christopher Rhoden Jr. was a current student at Piketon High School. 
 
 These are the worst days of his career, Burkitt said, because his community is so troubled. He said there wasn't much education happening inside the schools Monday but mostly just an outpouring of support and love. 
 
 He said that word of the marijuana operation at the Rhoden property doesn't change the facts in front of him. 
 
 "You don't condone someone breaking the law, but we've had eight people murdered," Burkitt said. "No accusations or circumstances can lessen the barbaric nature of what happened here. We are all just sad." 
 
 A reward of $25,000 is being offered for information in the case. Call 1-855-BCI-OHIO (224-6446).

 @RitaPrice ||||| A coroner says seven of the eight victims in killings targeting a southern Ohio family were shot multiple times. The father of one of the victims says he had no knowledge of marijuana growing operations at three of the four crime scenes. (Published Tuesday, April 26, 2016) 
 
 Seven of eight relatives slain in their southern Ohio homes were shot multiple times and some suffered bruising indicative of a struggle, according to autopsy results released Tuesday. 
 
 The victims — all members of the Rhoden family — appear to have been targeted. Authorities said the carefully planned slayings were carried out at four locations in the rural community of Piketon, east of Cincinnati. 
 
 Investigators uncovered marijuana growing operations at three of the crime scenes, according to Ohio Attorney General Mike DeWine, who cautioned that it's still too early to speculate about a motive. 
 
 "We're not ruling anything in; we're not ruling anything out," DeWine said. 
 
 He said one of the victims received a threat on Facebook but declined to go into detail. 
 
 Authorities also found evidence "consistent with cockfighting" at one of the properties, where birds were kept in "small, segregated cages," according to Jill Del Greco, a spokeswoman for Wine's office. 
 
 "Whether or not cockfighting was actually happening, we don't know, but it is part of the investigation," Del Greco said. 
 
 The victims have been identified as 40-year-old Christopher Rhoden Sr.; his ex-wife, Dana Rhoden; their three children, 16-year-old Christopher Rhoden Jr., 19-year-old Hanna Rhoden and 20-year-old Clarence "Frankie" Rhoden; Christopher Rhoden Sr.'s brother, 44-year-old Kenneth Rhoden; their cousin, 38-year-old Gary Rhoden; and 20-year-old Hannah Gilley, whose 6-month old son with Frankie was unharmed. Two other children, a 6-month-old and a 3-year-old, were also spared. 
 
 The Hamilton County coroner said Tuesday the victims — three women, four men and a 16-year-old boy — suffered wounds to their heads, torsos and other areas. 
 
 According to the autopsy report, one victim suffered a single wound, another was wounded twice, and the rest had three or more wounds. The report didn't specify which victim was which. 
 
 A woman who called 911 Friday morning reported finding "blood all over the house" and two bodies that appeared to have been badly beaten. The coroner said "soft-tissue bruising" on some of the bodies indicated a possible struggle. 
 
 Investigators have received more than 300 tips and are continuing to serve search warrants in an effort to identify the killer or killers, according to DeWine. He said 79 pieces of evidence have been sent to a state crime lab for testing and analysis. 
 
 Dana Rhoden's father, 64-year-old Leonard Manley, said Monday his daughter was not involved in anything illegal. 
 
 "They are trying to drag my daughter through the mud, and I don't appreciate that," said Manley, whose three grandchildren — Dana's children — were also among the dead. 
 
 Manley also said the assailant was able to get by his daughter's two dogs, who were wary of strangers.

– While authorities say some of the victims of Ohio's "execution-style" killings died in their sleep, others may have put up a fight. Autopsies show some members of the Rhoden family had soft tissue bruising, suggesting they resisted their killer or killers, the Pike County Medical Examiner said Tuesday, per NBC News. A 911 caller who reported "blood all over the house" noted it looked like someone had "beat the hell out of" at least one victim. The autopsies confirmed all eight victims—three women, four men, and a 16-year-old boy—were fatally shot; one victim was shot once, one was shot twice, and the remaining victims were shot three or more times, including one person who had nine wounds. Authorities have yet to present a motive, though marijuana-growing operations were found at three of the four crime scenes. Sources say 200 plants recovered were worth about $500,000, reports CBS News. Birds were also found in "small, segregated cages," which is "consistent with cockfighting," says a rep for the Ohio attorney general, per NBC New York. A prosecutor tells the Columbus Dispatch that the family was previously known to police for "altercations with people, that sort of thing ... nothing like this." Police have received 300 tips, sent 79 pieces of evidence for analysis, and are still serving search warrants, reports the AP. (Police say the youngest victim had been threatened on Facebook.)
