PLEASANTON -- The remains of a woman found in trash can in Pleasanton in May have been identified as a missing Stockton woman, and her suspected killer has been arrested.
Ana Flores-Pineda, 25, was found May 24 in Pleasanton, her body badly decomposed in a trash can on the side of the Dublin Canyon Road.
She was reported missing June 12 in Stockton.
Officers from the Pleasanton Police Department and the Stockton Police Department arrested Javier Prado Sandoval, 30, after serving him with a search warrant at his home on Rosemary Lane in Stockton on Wednesday.
Sandoval has been booked in the San Joaquin County Jail on suspicion of murdering Flores-Pineda. He is expected to be arraigned Friday in a Stockton courtroom.
Sandoval and Flores-Pineda were once in a relationship, but investigators don't know if they were still dating at the time of her death, Stockton police Office Joe Silva said.
In August, Pleasanton police confirmed they had joined forces with the FBI and the Department of Justice to try to get leads on the case that had previously yielded none.
Lt. Jeff Bretzing of the Pleasanton Police Department said at the time that though the collaboration had been ongoing since early in the investigation, federal agencies were taking a more extensive role in trying to help identify the woman by providing access to and searching databases outside the area.
Facial sketches and photos initially released of the woman's jewelry did not yield any leads.
In July, a forensic odontologist was brought in to analyze the victim's teeth. However, the analysis would only prove helpful if the woman's dental records were found in a database. It is unknown if the results of the tooth analysis helped identify the woman.
The woman's body was discovered after officers were called to Dublin Canyon Road on May 24 by someone who reported a suspicious-looking trash can sitting on the road.
Police found a body badly decomposed. The woman was believed to have been in her 20s, but her age could have spanned from 18 to 40 years old, according to police.
The coroner's office determined the woman was probably Asian or Latino with dark hair and was about 5-foot-6 and weighed about 130 pounds.
She was found wearing an Old Navy shirt and pajama bottoms. She was also wearing blue fingernail polish, red toenail polish and had three ear piercings in each ear with distinctive earrings. She had no tattoos or other markings.
This is Stockton's 61st homicide of the year. This surpasses last year's record high of 58.
