MINNEAPOLIS (WCCO) — An 18-year-old St. Paul man has been charged with allegedly shooting a Good Samaritan in the chest earlier this month.

Treheem Smith, who was arrested Tuesday, faces attempted second-degree murder in connection with the Sept. 2, 2015 incident.

Smith is accused of shooting a man who jumped out of a car to stop an assault on a vulnerable person at a light rail platform.

“This is a tragic case of a man who is shot coming to the aid of a crime victim,” Ramsey County Attorney John Choi said. “Our thoughts, prayers and good deeds as a community should be focused on his recovery. We will do everything in our power to seek justice for the victim.”

Authorities say investigators were able to identify two juvenile assailants involved in the incident, one of whom identified Smith. The two juvenile males, ages 14 and 15, have since pleaded guilty to first-degree aggravated robbery.

The victim remains at Regions Hospital. Surgeons needed to fix a lacerated liver and had to remove part of his pancreas, stomach and colon.
