Two more arrests have been made in the Tuesday shooting death of 17-year-old Bradley Brown, the son of a Prince George's County police officer.

It was Tuesday night about 7 p.m. that Brown was found gunned down in his own driveway in Bryans Road by Charles County Sheriff's deputies. With him was found a gun belonging to his police officer father. It was loaded and hadn’t been fired.

Keshawn Belasco, 16, and Mikayle Qawwee, 19, both of Waldorf, are now charged with first-degree murder, authorities announced Friday.

The first suspect to be arrested in this case was Darryl Edward Freeman, 17, of Waldorf. He was taken into custody on Wednesday and will be charged as an adult with first-degree murder.Belasco will also be charged as an adult.

According to the court papers, Brown had been selling THC vape cartridges and marijuana and advertising on Snapchat.

It was revealed in court documents that Brown had arranged to meet Darryl Freeman. But Friday in court in LaPlata, during a bond review for Freeman, prosecutors said Freeman had been planning a robbery not a buy and just days before the shooting texted a friend about buying a 9mm handgun. A 9mm was used to kill Bradley Brown.

According to court documents murder suspects Freeman , Qawwee and Belasco met up with Brown with the intention of robbing him of the THC vape cartridges Brown had advertised for sale on Snapchat. After they shot Brown it's alleged they took 10 of the illegal cartridges worth $300.

Freeman and Qawwee and Belasco are locked up and charged with first degree murder.
