UPPER MARLBORO, Md. (AP) — A former Maryland State Police cadet has been convicted in a crash that killed a Temple Hills woman. 

The Prince George’s County State’s Attorney’s Office said in a news release that 20-year-old Sebastian Reyes of Mechanicsville was convicted Thursday. Reyes was convicted of criminally negligent manslaughter and other offenses in the death of 59-year-old Karen Holt-Williams of Temple Hills.

Prosecutors say on Aug. 1, 2014, Reyes was driving a State Police vehicle on the Capital Beltway at a high rate of speed.

Police say Reyes used a crossover for emergency vehicles to head in the opposition direction. Reyes lost control of the vehicle and sideswiped a car driven by Holt-Williams.

Authorities say Holt-Williams’ car traveled across the interstate and hit a jersey wall. Holt-Williams died at a local hospital.
