A suspect accused of stabbing a man on a Charlotte Area Transit System commuter train on Friday is undocumented and was previously deported, according to authorities.

A social worker, described by colleagues as "remarkable" and "compassionate," has died from stab wounds she suffered when a patient armed with a steak knife allegedly attacked her inside a San Francisco hospital, according to authorities.

Howard claimed he only used the racial slur after being stabbed, but Edwards testified that the victim called him the word the moment he saw him.
