Mario Green, the man accused of killing his ex-wife in the Henry Ford Hospital shooting in Detroit, is in police custody.

The man had been on the run since he allegedly shot his ex-wife Friday morning and was presumed to be armed and dangerous.

Green, 53, reportedly got into an argument with his former spouse, Latricia Green, who worked at the Detroit-based hospital, in the basement of the facility. At some point, he pulled out a firearm, shooting her multiple times and killing her, Bettison said. It’s unclear how Green was able to gain entry to parts of the hospital.
