Javier Sandoval, 35, was sentenced June 12 for the killing of Ana Flores-Pineda, 25. Sandoval pleaded guilty to second-degree murder and was sentenced to 15 years to life.
Flores-Pineda's body was found inside a 45-gallon trash can on Dublin Canyon Road in Pleasanton on May 24, 2012. Her identity and the circumstances of her death were a mystery for months until Stockton police made the connection between the body and a missing person's report filed by her friends a few weeks after her disappearance May 2.
Stockton police initially looked in the Pleasanton area after Sandoval's cell phone was recorded being used in Pleasanton on the evening of May 3, but no connection was made between the body and Flores-Pineda's disappearance until Stockton detectives conducted a follow-up on the missing persons case.
Pleasanton police Sgt. Kurt Schlehuber said at the time that Flores-Pineda had been in the trash can for "a few weeks."
The young woman's body was badly decomposed and her identity had to be confirmed using DNA.
Stockton and Pleasanton police departments worked closely together to narrow the focus on Sandoval, who was arrested by Stockton police on Oct. 31.
Evidence indicated that Flores-Pineda was murdered in the Stockton home she shared with Sandoval.
It may not be the first time Sandoval killed. At the sentencing, San Joaquin County Deputy District Attorney Mark Ott filed a statement and included documents of the suspicious death of Sandoval's deceased wife, Jaqueline Estrada.
Those records indicated the former wife died of manual strangulation, which was how Flores-Pineda died.
