OAKLAND, Calif. (AP) - 1:30 p.m.
Prosecutors in Northern California say a paroled robber faces murder and attempted murder charges in the attack at a subway station against two sisters that left one of them dead.
They say 27-year-old John Cowell is set to be arraigned Wednesday in Oakland in the Sunday attack against 18-year-old Nia Wilson, of Oakland, and her 26-year-old sister, Letifah Wilson.
Alameda County prosecutors say he also faces parole violations charges.
Cowell was arrested Monday night on a Bay Area Rapid Transit train in the San Francisco Bay Area, about a dozen miles from the MacArthur station where the sisters were attacked.
His family says he has suffered from mental illness most of his life and failed to receive proper treatment.
Records show Cowell recently served two years for second-degree robbery.

Police in Northern California say they are investigating the death of a homeless man who was attacked at a subway station the day before a teenage girl was fatally stabbed on a transferring platform.
Bay Area Rapid Transit police say they are looking for a suspect who allegedly punched 47-year-old Don Stevens at the Bay Fair station on Saturday.
Authorities late Tuesday released images of the man they say hit Stevens to the side of the head with a closed fist. Stevens fell and struck his head.
He died at a hospital Sunday, the same day John Cowell allegedly stabbed 18-year-old Nia Wilson to death at the MacArthur station what authorities say was an unprovoked attack.
Cowell is scheduled to be arraigned Wednesday.
