Autopsy results have confirmed that a body found in the wilderness near a California canyon is that of missing army veteran Maribel Ramos, police announced Friday, and her roommate has been arrested for murder.

Ramos, 36, was set to graduate from Cal State Fullerton University later this month, and was last seen on surveillance video dropping off her rent check about 8:30 p.m. May 2 in Orange, Orange police Lt. Dave Hill said. 

Ramos's body was discovered at Modjeska Canyon on Thursday afternoon.

The murder suspect is Ramos's former 54 year-old roommate Kwang Chol "KC" Joy. 

Joy was taken in for questioning by Orange P.D. early Friday, and later arrested, suspected in her murder.

A motive remains unclear. 

Ramos served in the Army for eight years, including two tours of duty in Iraq and South Korea, before she was honorably discharged in 2008. She was majoring in criminal justice.

Maribel, who served 2 tours of duty in Iraq, was last seen at her apartment in Orange on May 2nd. 

Her family reported her missing the next day when she didn't show up for a scheduled veterans event and a softball game. Right before she disappeared, the family says Maribel had asked her roommate to move out.
