Her job is to question others, but now one high-ranking investigator finds herself on the other side of the law.
Karen Cabrera, a supervisor with the county Public Defender's Office is accused of hiding a witness. A witness allegedly beaten by her son.
Cabrera, 58, was arrested Friday at her home in Mission Valley, accused of conspiracy and witness tampering for hiding a witness to her son's domestic violence case.
An arrest warrant obtained Monday describes Cabrera's alleged involvement in the case filed against her son, Alejandro.
Last year he was charged with burning his girlfriend with a hair iron, punching and kicking her. Prosecutors say it was a beating that sent the woman to the hospital.
Shortly after, that woman missed a preliminary hearing in the case.
Investigators discovered Karen Cabrera traveled with the girlfriend to Acapulco, then returned on her own.
Credit card records also show Karen Cabrera bought those airline tickets, according to investigators.
Cabrera was home for comment Monday evening.
The District Attorney's office, police and sheriff's department all declined to comment.
She has since posted $50,000 bail and is scheduled to be arraigned April 13.
