PLEASANTON (KRON) -- It could be next week before we have more answers about exactly how a Pleasanton woman and her teenaged daughter ended up shot to death on the floor of the family home.

Alameda County Coroner's office workers say 37-year-old Amy Freeman Burton and her 13-year-old daughter, Ainsley Freeman each died from a single gunshot wound to the head.  The bullets removed from both victims are consistent with the kind of handgun found near the victims but authorities won't know for sure if that gun killed them until more tests are conducted next week.

Authorities say evidence suggests the teenager did not shoot herself although that's not yet conclusive.  They're also not ruling out the possibility that Amy Burton fired the shots.  Police are not yet saying this is a case of murder-suicide.

Investigators say the will continue to follow all leads.  Christopher Burton, Amy's husband and step-father to Ainsley, remains cooperative with investigators police say.  Burton says he found the bodies Tuesday at the family home on Stacey Court in Pleasanton.
