In the first, which occurred on May 7, 37-year-old Amy Freeman Burton and her 13-year-old daughter Ainsley Freeman, were found with fatal gunshot wounds at their home on the 3200 block of Stacey Court.
The autopsy done in that case yielded little to resolve the case, although preliminary results indicated that 13-year-old Ainsley Freeman did not shoot herself. The coroner's report said it was "unclear" whether 37-year-old Amy Freeman Burton's wound was self-inflicted.
The Pleasanton Police Department has been promised by the Alameda County Sheriff's Office crime lab that results would be coming soon each week since the incident, according to police Sgt. Kurt Schlehuber.
Freeman and her mother were each shot once in the head, according to the Alameda County Coroner's Office. Police have not released the type of pistol involved. Neither of the two guns found at the home is registered, according to a Pleasanton police news release, but one was located in the general area of the two victims.
In the other death, police are awaiting a lead to break the case of a woman whose body was found May 24 inside a trash can in a wooded area on Dublin Canyon Road, not far from its intersection with Laurel Creek Drive. So far, none of the tips received by police has yielded any results, Schlehuber said.
"At this point, we've got tons of leads, but none of them have panned out," Schlehuber said, adding the department has been combing through missing persons cases without luck.
"We've asked the DOJ to help us out," he said. "They've got a broader range of resources."
The autopsy could not determine the exact time or cause of death, police said.
The coroner determined the woman had shoulder-length dark hair, was 5 feet 6 inches tall and weighed about 130 pounds, police said. She was found wearing an Old Navy shirt and pajama bottoms.
A forensic anthropologist determined the woman to be between her mid-20s and 40 years of age, according to police. She is believed to be either Asian or Hispanic, although it is also possible that she is Caucasian with Asian traits or Native American. The woman was wearing blue fingernail polish, red toenail polish, and she had three piercings in each ear. She has no tattoos or distinctive markings.
Schlehuber said police hope the distinctive earrings will break the case.
"I would hope that someone would recognize those, along with the composite sketch," he said. "I know the community is really concerned about this. We just want to get the information out."
