Prince George’s County police on Saturday identified a second suspect in connection with an armed carjacking that led to a pursuit into the District and ended with a head-on collision with a school bus in Southeast Washington.

Christopher DeWayne Barnes, 20, of the 1500 block of Alabama Avenue SE, is charged in a warrant with carjacking and a weapons violation, according to authorities. Police said they were searching for him on Saturday.

Police arrested another suspect shortly after the chase ended, charging Malik Hasam Wilkins, 17, of the 5300 block of Clay Terrace SE, with carjacking, fleeing and eluding, and weapons violations. He was charged as an adult and is being held without bail in the Prince George’s County Detention Center.

The incident began Thursday morning in District Heights when police said two men with guns and wearing ski masks forced a driver out of a Mercedes and drove off. Police said officers quickly located the car and chased it for about a mile into D.C.

Police said the driver tried to turn off Ridge Road onto Texas Avenue and lost control, hitting a car stopped at a red light. A pregnant woman and a teenager were injured in that crash. Police said the driver continued on Texas Avenue and hit the school bus head-on.

One adult and one child aboard the bus suffered minor injuries, D.C. police said. Another adult and child on the bus were not injured. Police said the occupants of the Mercedes ran, but one was caught near the scene, and a gun was recovered.

Prince George’s County police said a cash reward is being offered for information leading to an arrest and indictment of Barnes. Anyone with information is urged to call 301-772-4425 or Crime Solvers at 1-866-411-TIPS.
