As Ricky Best, a 53-year-old Army veteran, lay dying on the train, police say a man sneaked up to him, took his backpack and slipped his wedding ring off his finger.

Police released photos and surveillance video on Thursday of the middle-aged man, who wore a mullet haircut, a baseball cap, a black T-shirt with an image of Marilyn Monroe and an American flag, and black shoes.

The video showed him exiting the station after the attack holding two backpacks. In his right hand was a black one that matched that of Best’s, which police said had “personal items important to the Best family.”

A day later, officers said they found the man they were looking for.
