 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. ||||| The California man who abducted a teenage family friend and tortured her mother and 8-year-old brother before killing them exchanged more than a dozen calls with the 16-year-old girl in the hours before the slaying.

 Exactly how James Lee DiMaggio tortured them or why he and Hannah Anderson exchanged about 13 calls wasn't immediately clear, but the new details in court papers fueled questions about how and why he targeted his best friend's family and fled with a girl who has said she felt uncomfortable around him. 
 
 Firefighters found the body of Christina Anderson, 44, near a crowbar and what appeared to be blood next to her head. DiMaggio is believed to have shot and killed their family dog, found under a sleeping bag in the garage with blood close to its head. 
 
 Investigators found 8-year-old Ethan's body as they sifted through rubble. 
 
 DiMaggio "tortured and killed" the mother and son, San Diego County sheriff's Detective Darren Perata wrote, offering no elaboration, in the warrants released Wednesday. Hannah was rescued days later in the Idaho wilderness, where authorities killed DiMaggio in a shootout. 
 
 The warrants do not indicate the time, duration or content of the calls that DiMaggio and Hannah exchanged before she was picked up at cheerleading practice Aug. 4, hours before firefighters found DiMaggio's burning garage in Boulevard, a rural town 65 miles east of San Diego. 
 
 Jan Caldwell, a San Diego County sheriff's spokeswoman, said they may have been discussing pickup times. 
 
 Investigators who searched DiMaggio's home found letters from Hannah, an incendiary device, a handcuff box and "arson wire," according to a warrant posted on the website of KFMB-TV. The warrant does not elaborate on the letters or nature of the devices. 
 
 DiMaggio was extraordinarily close to both children, driving Hannah to gymnastics meets and Ethan to football practice. The warrants say the former telecommunications technician took Hannah on multi-day trips, most recently to Malibu and Hollywood. 
 
 Hannah acknowledged being uncomfortable around DiMaggio before the ordeal, saying on a social-media site earlier this week that he once told her that he was drawn to her. "He said it was more like a family crush like he had feelings as in he wanted nothing bad to happen to me," she wrote on the ask.fm site. 
 
 Hannah said she didn't tell her parents because DiMaggio was his father's best friend "and I didn't want to ruin anything between them." 
 
 She said she didn't learn that her mother and brother had died until authorities told her in the hospital after she was rescued. She said she cried all night. 
 
 San Diego County Sheriff Bill Gore has been adamant that Hannah was an unwilling victim from start to finish. "I can't make it any clearer," he said at a news conference Monday. 
 
 Hannah's father, Brett Anderson, declined to take questions after making a brief statement at a fundraiser for the family in Lakeside, an east San Diego suburb and Hannah's hometown. Caldwell said investigators may offer a more detailed account in the future but that some questions may never be answered. 
 
 "Right now she's with her family and, of course, with some friends, and she's just happy to be here," Brett Anderson told reporters outside the Boll Weevil restaurant, which hosted the fundraiser. 
 
 Anderson said he spoke with the horseback riders who saw the pair in the Idaho wilderness and alerted authorities, thanking them for saving his daughter's life. 
 
 Hannah Anderson was mobbed by reporters as she entered the restaurant and did not make a statement. 
 
 DiMaggio was shot at least five times in the head and chest, according to the Valley County, Idaho, coroner, who was unable to determine a precise number of gunshot wounds. His body was cremated Tuesday near Los Angeles. 
 
 On her ask.fm social media account, Hannah said she "basically" stayed awake for six straight days and repeatedly told her captor she was hungry. She couldn't escape because DiMaggio had a gun and "threatened to kill me and anyone who tried to help." 
 
 Asked if she would have preferred DiMaggio got a lifetime prison sentence instead of being killed, she said, "He deserved what he got." 
 
 The ask.fm account was disabled but there were postings on an Instagram account linked to Hannah's now-disabled page. "Dad is not taking this very well," she wrote late Wednesday. "None of us are but please watch over him. I'm all he's got left. Even though your gone we are still a team. Love and miss you. "

– 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.
