A high-ranking investigator with the San Diego County public defender's office has pleaded not guilty to hiding a witness in her adult son's domestic violence case.
Karen Cabrera was arrested April 3 at her home in Mission Valley, accused of conspiracy and witness tampering for hiding a witness.
The 58-year-old investigator's adult son and his long-time girlfriend were involved in a domestic violence incident in May.
An arrest warrant obtained three days later described Cabrera's alleged involvement in the case filed against her son, Alejandro.
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.
The girlfriend appeared in court one week after Cabrera's son pleaded guilty.
The District Attorney's office, police and sheriff's department all declined to comment.
Cabrera has posted $50,000 bail.
