Suspect’s wife arrested in hammer attack on Chino student

The wife of a man suspected of attacking a 16-year-old Chino High School student with a hammer Thursday and leaving him in critical condition has also been arrested.

Raina Renee Crawford, 40, was arrested by Chino police Thursday evening at an apartment complex across the street from the high school, according to records from the San Bernardino County sheriff’s office.

Michelle Van Der Linden, a spokeswoman for the city of Chino, said Crawford is suspected of aiding her husband, 48-year-old Gregory Undra Richmond, during the alleged attack, which happened across the street from the school.

The boy was airlifted to a hospital, where he remains in critical condition, Van Der Linden said.

Van Der Linden said it was unknown what prompted the attack, or whether Richmond and the boy knew each other.

Police responded to a call reporting the attack at about 1:17 p.m. Thursday. Chino High School and nearby Walnut Avenue Elementary were placed on lockdown while police searched for Richmond, who was arrested a few blocks from the school “within the hour.”

Crawford was arrested a few hours later at Richmond’s home.

Both have been booked for attempted murder and are being held in lieu of $1-million bail. They are scheduled to appear at the Rancho Cucamonga Superior Court on Jan. 21.

Reached by phone, a woman identifying herself as Richmond’s mother declined to comment.
