A man has been charged in the fatal shooting of local rapper Phil Da Phuture during a robbery at a Northwest D.C. dispensary where the rapper worked, D.C. police said.

On Monday, 21-year-old Trenton Collins was arrested and charged with first degree murder while armed.

Police said Collins had entered a Northwest D.C. cannabis dispensary in March and demanded money from the patrons and employees. During the robbery, he fired a shot, fatally striking 41-year-old Philip Prendergast after he had cooperated with Collins. The suspects took the property and money before fleeing the scene, according to police.

Prendergast later died at a hospital.

Police are continuing their search for the second suspect in the robbery and have released surveillance video from the incident:
