PLEASANTON -- A mother shot her 13-year-old daughter, then turned the gun on herself in a May 7 shooting in their suburban home, police said Friday in releasing the results of their investigation into the case.
"Investigators have determined that Amy Freeman Burton shot and killed her daughter, Ainsley Freeman, and then shot and killed herself," Lt. Jeff Bretzing said. "This was determined by a myriad of evidence, including physical and forensic evidence. We are confident based on the evidence there were no other people involved in this incident."
Freeman Burton, 37, and her daughter, Ainsley were found shot in their Stacey Court home the evening of May 7.
The day of the shooting, police responded to a 911 call reporting a shooting about 6 p.m. and found Freeman Burton dead from a gunshot wound. Her daughter, Ainsley Freeman, was also wounded by gunfire and was taken to Eden Medical Center in Castro Valley.
The call to police came from Christopher Burton, Amy Freeman Burton's husband and Ainsley's stepfather. Officers recovered two handguns in the home, including one found near the victims.
The handguns were tested relative to the location and nature of the wounds to determine that Freeman Burton was responsible for both shootings, Bretzing said. The results were made available 10 weeks after the incident, in part because the Alameda County crime lab was also working other cases.
Police said others, originally deemed to
Freeman Burton's mother, Linda Walp, who lives in Missouri, told a St. Louis newspaper in May that her daughter told her she had been receiving death threats after she told police and the FBI about a man involved in a child porn ring trying to befriend Ainsley via the Internet.
Bretzing said police have no record of Freeman Burton reporting death threats. Pleasanton police and the FBI did investigate a report that Ainsley had been text messaging with a suspicious man. The investigation revealed it was a 16-year-old boy from Tennessee, and that no crime had been committed.
Freeman Burton and Ainsley Freeman moved from Missouri to Pleasanton in December to join Christopher Burton, who took a tech job in the Bay Area last year.
On May 9, Pleasanton police announced that preliminary autopsies couldn't determine if it was a murder-suicide. Police said at the time that they were still treating it as a homicide investigation as they awaited more test results on the bullets and a handgun found near the bodies.
Early autopsy results showed that both suffered single gunshot wounds to the head, and that Ainsley Freeman most likely didn't shoot herself, Lt. Jeff Bretzing said at the time. He added that results were unclear on whether Amy Freeman's wound was self-inflicted, but it was not being ruled out and police were awaiting lab test results.
Freeman Burton's motive in the shooting death of her and her daughter remains unknown.
"We still just don't know," Bretzing said. "We have no concept of Amy Freeman Burton's state of mind."
