Concerned mom had taken murder suspect to mental health clinic

BAKERSFIELD, Calif. (KBAK/KBFX) A man accused of murdering a woman who was reported as missing from Ventura pleaded not guilty in Kern County on Friday to a first-degree murder charge.

Eddie David Rivas, 20, also pleaded not guilty to battery and resisting authorities after he was arrested in the murder of 18-year-old Mia Ramirez, whose body was found on June 11, wrapped in a rug in Rivas' mother's garage.

His plea came on the same day that newly released court documents revealed details regarding how Ramirez was killed, but still don't identify a potential motive for her killing or how her and Rivas may have met.

An autopsy revealed that Ramirez died from multiple stab wounds to the face, neck, chest and abdomen areas. She was also missing several body parts by the time her body was found.

During an interview with the Kern County Sheriff's Office, Rivas' mother Clara Rivas went into detail about the days leading up to the discovery of Ramirez's body.

Rivas told authorities she saw her son on June 9, coming out of her garage with blood on his hands.

The following day, she took Eddie Rivas to the Mary K. Shell Center mental health clinic, where she claims he filled out and signed a questionnaire. Of the survey's 25 questions, documents reveal that Eddie Rivas checked the "yes" box when asked, "Do you think you may harm yourself or someone else?"

Clara Rivas also said her son has bipolar disorder.

Hours before the body was found, Clara Rivas asked her boyfriend to locate the cause of a foul odor coming from their garage. After checking, Rivas' boyfriend discovered a shoe inside the rug and assumed it was a body.

It is unclear how long Ramirez's body was in the garage, but authorities estimate no more than a few days.

Eddie Rivas was released from prison in November, where he served time for assaulting an officer following a high-speed pursuit in 2011.
