The woman whose body was found inside a garbage can in Pleasanton in May has been identified, and police arrested her alleged killer today.

Police have confirmed the woman to be Ana Flores-Pineda, 25, of Stockton. Her body was found inside a trash container on Dublin Canyon Road on May 24.

Police detectives from Pleasanton and Stockton arrested Javier Prado Sandoval, 30, also from Stockton, this morning.

Investigators determined Flores-Pineda was the victim of a homicide that occurred in the city of Stockton. Pleasanton police Sgt. Kurt Schlehuber said Flores-Pineda had been in the garbage can for "a few weeks."

A missing persons report led Stockton police to the body found in Pleasanton, Schlehuber said.

"Through their investigation, they contacted the Alameda County Coroner who confirmed they had an unidentified Jane Doe," he said. The body was linked to Flores-Pineda through DNA analysis.

Stockton detectives conducted follow-up on the missing persons case. Working in conjunction with Pleasanton detectives, they were able to identify the deceased female located here as Flores-Pineda, according to a police news release.

Sandoval was to be booked into the San Joaquin County Jail. The investigation is ongoing and further details regarding this case will be released at a later date.

"The motive definitely is domestic violence," said Stockton police Officer Joe Silva, the department's public information officer. "They were in some type of relationship."

Silva credited Pleasanton police for their help in breaking the case.

"It's been a thorough investigation with both agencies," Silva said. "We couldn't have made this arrest without the Pleasanton Police Department."

The two agencies are continuing to cooperate.

"We're still working on various aspects of this case to support Stockton police," Schlehuber said.

Pleasanton police followed up through a number of approaches, including a forensic anthropologist's sketch and the release of photos of earrings from the woman's body. They also forwarded DNA to a national database, and did a search of dental records.

"We had contacted a sculptor, an artist to do a sculpture, a bust, that was our next step," Schlehuber said, adding that the lead to Stockton came in at the same time.
