An arrest has been made in the death of a Nardin Academy graduate in Maryland.

According to news reports there, 24-year-old Gregory Terrell Jones was charged with two counts of first-degree murder in the deaths of 34-year-old Ashley Dickinson and 29-year-old Joshua Frazier.

The two were found in a parked car about 45 minutes north of Washington on February 15. The vehicle was still running.

Investigators say they determined Jones' involvement after he shot at police two days after the double-homicide.

His cousin, 25-year-old Tyshon Jones, was shot dead by officers during that incident.

Police say they matched the bullets in Gregory's gun to those used in the double-homicide.
