OXON HILL, Md. — Prince George's County police have arrested a man who shot and killed an Uber driver and his passenger in Oxon Hill late Tuesday night.

The suspect, identified Wednesday as Aaron Lanier Wilson, Jr., 42, confessed he was high on PCP at the time of the shootings, police said during a news conference Wednesday afternoon. 

Police said Wilson was arrested at his home on the 10000 block of Indian Head Highway Wednesday morning.

The shooting happened around 9:45 p.m. Tuesday night on Rt. 210/Indian Head Highway at Bald Eagle Road.

Police found both victims in a stopped vehicle with gunshot wounds to the upper body. They were pronounced dead at the scene, according to police.

The driver was identified Wednesday as 46-year-old Beaudouin Tchakounte, of Frederick, Md. Tchakounte was a father of two, according to police. The rider was identified as 32-year-old Casey Xavier Robinson of Accokeek, Md., police said.

Authorities said Tchakounte picked up Robinson and later picked up Wilson in an Uber pool -- another ride-share option offered by Uber. Wilson got into the Uber and minutes later shots were fired.

Wilson did not know either person inside the vehicle, according to detectives. He is now charged with first- and second-degree murder.
