 The Medical Examiner’s Office on Monday released the autopsy reports on Christina “Tina” Anderson of Lakeside, and her 8-year-old son, Ethan, whose bodies were found last month on the burning Boulevard property of family friend James DiMaggio. 
 
 Sheriff’s officials have said DiMaggio killed both of them and kidnapped Anderson’s daughter, Hannah, 16, then remotely set incendiary devices in his house and detached garage. 
 
 Authorities have said Christina Anderson, 44, died of blunt-force trauma to the head and that a crowbar was found near her body. 
 
 The autopsy report said at least 12 impact sites were on her head, and that her ankles were bound by plastic cable tie. Duct tape was wrapped around her neck and mouth. She had abrasions and lacerations on her right arm and left leg, and her right arm was fractured. She had an incision wound on her neck that the report said was likely inflicted after she died. 
 
 Her body was found in the garage, along with that of the Anderson family dog, which had been shot. Firefighters were able to extinguish the blaze in the garage when they arrived the night of Aug. 4. 
 
 Ethan’s body was found in the charred remains of the separate two-story house, which was fully engulfed when firefighters arrived. The autopsy said Ethan most likely died due to the fire, but that he also had skeletal fractures, and trauma could not be ruled out as a possible cause of the fractures. 
 
 Ethan’s body had been so badly burned that authorities earlier said he had to be identified through DNA. His father, Brett Anderson, said earlier that his DNA was used. 
 
 DiMaggio, 40, was shot and killed by FBI agents in an Idaho wilderness on Aug. 10, six days after Hannah was abducted. She was rescued by the agents and returned to her family. 
 
 Sheriff’s homicide Lt. Glenn Giannantonio said Monday that sheriff’s officials had no comment on the autopsy reports and would not be releasing further information about their investigation. ||||| (CNN) -- James DiMaggio's family is requesting DNA samples from the family of Hannah Anderson, the 16-year-old girl he's accused of kidnapping and whose mother and brother were found dead in his burned home. 
 
 The reason? They want to know if he was Hannah and 8-year-old Ethan's biological father, a family spokesman said. 
 
 "We are going to be requesting from the Anderson family that we try to get DNA samples from Hannah. And if they have anything left from Ethan, that we get a DNA sample," family spokesman Andrew Spanswick told CNN affiliate KGTV. "There has been a lot of rumors that Jim might be the father of either or both children." 
 
 Reached by CNN, Spanswick said DiMaggio's sister, Lora, is making the request, but would not elaborate further. 
 
 A representative for the Anderson family appeared to shoot down the theory. 
 
 "Brett and Tina Anderson did not meet Mr. DiMaggio until the sixth month of Tina's pregnancy with Hannah. Brett Anderson's DNA was used to identify the body of his dead son Ethan Anderson," the family statement said. 
 
 And David Braun, Tina Anderson's uncle, reacted angrily to the idea. 
 
 "I would tell them to shut up with their accusations and their implications up until after the funeral, until after my precious Tina and precious Ethan are buried -- the family members that your family murdered," Braun said. "That's what I would tell them." 
 
 Mother, brother laid to rest 
 
 A complex case 
 
 There was a time when the Hannah Anderson abduction case seemed clear-cut. 
 
 DiMaggio, a close Anderson family friend, allegedly kills Hannah's mother and brother, burns his house down, kidnaps Hannah and goes on the run. After a frantic week-long manhunt, he is spotted in the Idaho wilderness and shot dead by an FBI agent. Hannah is safe and reunited with her father. 
 
 That was on August 10. 
 
 With each passing day since then, the case has taken on added complexity. 
 
 On Monday, the Anderson family spokeswoman told CNN that DiMaggio, 40, left a life insurance policy from his job as a telecommunications tech that named Hannah and Ethan's grandmother, Bernice Anderson, as the beneficiary. 
 
 Stacy Hess, the spokeswoman, did not know the dollar amount but other media outlets put it at around $110,000. 
 
 "We find it very strange that he has left all this money without any explanation," Spanswick told KGTV, in explaining the need for the DNA tests. 
 
 "It states specifically that he didn't want to give it to either parent cause he didn't trust them," Spanswick said, referring to Hannah's parents. 
 
 The Anderson children called DiMaggio "Uncle Jim." One search warrant referred to Hannah's mother as DiMaggio's "best friend's wife."

 Hannah spotted with captor 
 
 Then there is this. 
 
 Hannah was seen in a car with DiMaggio about 20 hours before he allegedly set fire to his house, police said Tuesday. 
 
 The two were seen in DiMaggio's blue Nissan Versa just after midnight Sunday, August 4, said San Diego County Sheriff's Department spokeswoman Jan Caldwell. She confirmed reporting from the Los Angeles Times that the two were spotted at a U.S. Border Patrol checkpoint. 
 
 Caldwell did not say what the two were doing together, or if Hannah Anderson was with DiMaggio voluntarily. 
 
 CNN was unable to get an Anderson family response to this revelation. 
 
 Actions raise eyebrows 
 
 Some of Hannah's actions have raised eyebrows in some quarters. 
 
 A friend of Hannah's told authorities "DiMaggio took her on multiple day trips," according to a search warrant. 
 
 The same document said phone records indicate the two "called each other approximately 13 times" shortly before both their phones were turned off around 4 p.m. (7 p.m. ET) on August 4. 
 
 That was around the time that Hannah was picked up from cheerleading practice at Sweetwater High School, the warrant says, while noting it wasn't known who picked her up. 
 
 The same document says that a fire was reported at around 8 p.m. later that day at DiMaggio's two-story log cabin and a detached garage in Boulevard, California. 
 
 After battling the fire, authorities found the bodies of the teenager's mother, Christina Anderson, and Ethan. 
 
 An affidavit claimed that both had been "tortured and killed" by DiMaggio, who then set his home and garage ablaze.

 A fire captain found Christina Anderson face down in the garage, covered with a tarp, and with a crowbar and what appeared to be blood next to her head. 
 
 The manhunt 
 
 An Amber Alert was issued the next day. 
 
 The ordeal ended about 1,000 miles from where it started, on August 10, when an FBI tactical agent shot and killed DiMaggio in the Frank Church-River of No Return Wilderness, about 15 miles outside Cascade, Idaho. 
 
 As to Hannah, she was physically unharmed and soon returned to her family in Southern California. 
 
 The teenager hasn't spoken publicly or with reporters since the ordeal. But she did field anonymous questions on the website ask.fm, according to Alan MacNabb, whose son is one of Hannah's closest friends. 
 
 In those comments, she said DiMaggio had apparently set some kind of a timing device to start the blaze at his home. She also said she did not want to go with her "dad's best friend" and that, had she tried to escape from him, "He would have killed me." 
 
 Search finds 
 
 Friend: Hannah speaks about kidnapping on social media 
 
 San Diego County deputies searching DiMaggio's charred home found a handwritten note, handcuff box, camping equipment, a DNA swab kit, two used condoms and letters from Hannah, according to an affidavit. 
 
 Contents of the letters and the handwritten note were not revealed in the affidavit.

– Christina Anderson, mother of kidnapped teen Hannah Anderson, was bound and gagged before she was killed by at least a dozen blows to the face and head, according to newly released autopsy results. Her mouth and neck bore "multiple layers" of duct tape. The 44-year-old also had a broken arm and a slashed throat, although the latter apparently occurred post-mortem, the Los Angeles Times reports. A crowbar was found near her body. An autopsy on the badly burned body of her 8-year-old son, Ethan, was unable to pinpoint an exact cause of death. According to the report, "It is possible that he died of thermal burns without smoke inhalation in the house fire" that consumed the home of family friend James DiMaggio, though there were fractures to his skull that could have been caused by either the fire or DiMaggio. Police believe DiMaggio carried out both murders before kidnapping 16-year-old Hannah. He was shot and killed by FBI agents six days later. A police spokesman had no comment on the autopsy results and said they would not be releasing further information on their investigation, reports the San Diego Union-Tribune.
