OAKLAND, Calif. — Authorities say the man suspected of killing seven people at a California Christian college is on a hunger strike.

Alameda County Sheriff's Office spokesman Sgt. J.D. Nelson said Monday that One Goh has not eaten since his April 3 arrival at the Santa Rita Jail in Dublin.

Nelson said Goh has lost about 20 pounds since his arrest and was moved to the jail infirmary on Friday.

Goh has been charged with seven counts of murder and three counts of attempted murder for the April 2 shooting rampage at Oikos University in Oakland.

He has not yet entered a plea.
