Two brothers in Anne Arundel County were charged last week in the 2013 killing of a man who was scheduled the testify against one of the brothers in court.

Shar-Ron Charles Mason, 19, died of a gunshot wound inside a home in Odenton at about 3:35 a.m. on Dec. 10. Two months earlier, Mason had been involved in a physical altercation in his front yard with Bashunn Christopher Phillips, now 20. Lieutenant T.J. Smith said that Mason’s grandfather broke up that fight, and Phillips was charged with assault.

At the time that he was slain, Mason was expected to testify at Phillips’s trial a few weeks later.

Smith said that Phillips may have killed Mason to prevent him from testifying against him. “We believe that contributed. That’s one of the theories,” he said.

On Friday, an Anne Arundel County grand jury indicted Phillips on charges including first-degree murder. He is currently incarcerated on an unrelated weapons offense, police said.

His brother Tymaine Kenard Phillips, 17, was arrested Friday in the case. Police said Tymaine Phillips tried to hide evidence after Mason’s killing. He was charged as an adult with serving as an accessory after the fact and with carrying a handgun.
