A St Joseph woman was killed and another was critically hurt in a rollover accident early Tuesday morning in the 33-hundred block of Duncan. Investigators believe excessive speed and alcohol may have played roles in the crash.

St Joseph Police Captain Kevin Castle identifies the driver as Alexandra Bracken, who was killed.  The passengers were identified as Sylvia Peterson who was critically hurt, and Dallas Rails who was injured but not transported to the hospital.

Both Bracken and Peterson were ejected from the vehicle.
