Two teenagers shot a Good Samaritan who helped them pull an SUV out of a ditch, police say.

North Charleston, South Carolina, police spokesman Spencer Pryor said 45-year-old Chadwick Garrett helped two teenagers pull a Dodge Durango out of a ditch at 11PM Monday when the teenagers robbed and fatally shot him.

Garrett died at the scene, the Charleston County Coroner’s Office said.

Pryor said police arrested 17-year-old Deon Antonio Frasier and 19-year-old Michael Odell Anthony Dupree-Tyler about 6 miles away from the scene.

Both suspects have been booked into jail Tuesday morning and face murder charges. Fraiser also faces an additional charge of possession of a firearm during a violent crime, the Associated Press reports.

Frasier was free on a $10,000 bond for possession of a stolen vehicle, The Post and Courier reports.

Dupree-Tyler had been booked eight times before since July 2014 and pleaded guilty to one charge of possession of a non-narcotic controlled substance, according to The Post and Courier.

The victim, Garrett, had an arrest record dating back to 1995 when he was brought up on drug charges and domestic violence.

He served a year of probation for possession of cocaine in 1995 and six-months probation for third-degree assault and battery in 2010, The Post and Courier reports.

This was North Charleston’s 21st homicide this year.
