CHINO (AP) — Officials say the wife of a suspect has also been arrested in a hammer attack that left a Southern California high school student critically injured.

San Bernardino County jail records show 40-year-old Raina Renee Crawford and her 48-year-old husband Gregory Richmond were being held Friday night on $1 million bail on suspicion of attempted murder.

Van Der Linden tells the Los Angeles Times Crawford was arrested later Thursday for aiding her husband during the attack.

The boy remains in critical condition.
