Boyfriend charged in missing California woman's death, cops say. Her body has not yet been found.

A California man is accused of killing his girlfriend, who was reported missing a month ago.

But, authorities have yet to find her remains.

The Fresno County Sheriff’s Office arrested 41-year-old Ramon Jimenez on murder and domestic violence charges in the death of his girlfriend, Missy Hernandez, officials announced.

Hernandez, a.k.a. Missy Perez, 30, had been missing since Dec. 7. The Fresno County District Attorney’s Office is “confident it can successfully prosecute this case,” though she has not been found yet, according to The Fresno County Sheriff’s Office.

Jimenez has been in jail since Dec. 8, after he was arrested for a previous domestic violence incident. Officials tacked on a murder charge to his record last week.

Hernandez was last seen leaving an art show with Jimenez in downtown Fresno on the night of Dec. 7, according to the Fresno County Sheriff's Office.

The next day, friends contacted the Sheriff’s Office to check on Missy’s well-being because they were unable to get ahold of her, and considered it unusual for Hernandez to not respond in a timely manner, officials said

A deputy responded to her home on the 6000 block of South Chestnut Avenue on Dec. 8.

The deputy reportedly did not find Hernandez, but spoke with Jimenez and recognized him as a person wanted for domestic violence against Hernandez in October. The deputy took Jimenez into custody, according to the sheriff's office.

On Dec. 9, friends of Hernandez went to her house and were able to get inside. They told authorities Hernandez was nowhere to be found, but they found evidence that she may be injured and in need of help.

Deputies, homicide detectives and the Crime Scene Unit responded to the home to collect evidence and deemed Missy's disappearance suspicious. Detectives identified Jimenez as a person of interest and made a request to a judge that he be held without eligibility for bail, which was approved, according to the sheriff's office

During the month-long investigation, detectives developed forensic and digital evidence, "including DNA reportedly indicating a violent act took place."

Sheriff's said digital evidence showed possible locations where Hernandez might be but were unable to find her. Based on the evidence and the length of time Hernandez has been gone, detectives have reason to believe she is dead and Jimenez is responsible for her death.
