Maryland State Police investigators have identified the man killed in Thursday’s crash that shut down the Outer Loop of the Beltway for nearly an hour as 28-year-old Erick Francis Corsino Avila, authorities said.

Avila, of Hyattsville, was standing on the Beltway’s shoulder, preparing to change a flat tire, when the crash occurred about 6 p.m. just west of the I-95 split in the College Park area, authorities said. He was positioned between his own Cadillac and a friend’s Toyota Highlander when a Toyota Camry plowed into the back of the Highlander, authorities said. The crash pushed the Hylander into Avila, and the impact of that threw him into the back of his own Cadillac, authorities said.

Avila was transported to a nearby hospital, where he was later pronounced dead, authorities said. Four others, including the driver of the Camry and two children who were in the Highlander, were also injured in the crash and hospitalized but are expected to survive, authorities said.

Police identified the driver of the Camry as Aduayi Akueson, 37, of Gaithersburg. Sgt. Mark Black of the Maryland State Police’s College Park Barrack said it remains unclear why he veered onto the shoulder of the Beltway where two cars were stopped, but troopers did not initially detect any signs of alcohol use on the scene.

Akueson has not been charged with any crimes, authorities said.

Avila had been traveling with his 28-year-old girlfriend just before the crash, and they had called some friends for help in changing the tire, Black said. One of those friends, 33-year-old Dominga Danyris Acevedo, of Greenbelt, and her 7- and 8-year-old sons, were injured and taken to the hospital after the crash, police said. The children were buckled into seats in the back of the Highlander when the crash occurred, police said.
