GARLAND, Texas — A man was arrested and charged with intoxication manslaughter in connection with a chain-reaction crash that left a pedestrian dead on the highway, according to the Garland Police Department.

Just after 9 a.m., Monday, June 22, 2020, the Garland police responded to a crash involving a pedestrian on northbound Interstate-635, also known as the LBJ Freeway, just north of Centerville Road. 

"Investigators believe two vehicles were driving at a high rate of speed northbound on the freeway," according to the department. "One of the vehicles, a grey Dodge Challenger, struck a grey Jeep Liberty, causing both vehicles to lose control."

"The Jeep Liberty struck a pedestrian who was walking on the right shoulder of the freeway," stated the department. "The pedestrian was pronounced deceased at the scene."

The pedestrian has been identified, but the name has not been released pending notification of next of kin.

Police say the driver of the Challenger, who has been identified as 26-year-old Aldamion Riles, remained on scene. 

"The investigation led officers to believe Riles was impaired," stated the department.

Riles was subsequently arrested and charged with intoxication manslaughter. Police also found a handgun that belonged to Riles, resulting in additional charge for unlawful carrying of a weapon. He is being held in the Garland Detention Center and is awaiting arraignment.
