Police Wednesday charged 18-year-old William Robbins with robbery and 20-year-old Dyson Williams with second degree murder and robbery. It wasn't clear if they had lawyers yet.
The Tuesday morning crash, which also injured four people, occurred after police identified a car believed to be driven by three suspects wanted in an earlier armed robbery.
Police arrested the driver, but the passenger slid into the driver's seat and sped off with the other suspect, slamming into a minivan a few blocks away.
Two pedestrians were critically injured, and Sister Mary Celine Graham later died.
