WASHINGTON — A man is in the hospital with life-threatening injuries after being struck by a car Thursday morning in Rockville, Maryland.

Police say they received a call at 6:15 a.m. for a pedestrian-involved collision at the intersections of Hungerford Drive (Maryland Route 355) and Frederick Avenue.

Upon arriving they found 61-year-old Dingguo Guo of Rockville, suffering from life-threatening injuries. He was taken to the hospital for treatment. The driver of the 2003 Lexus ES300, 56-year-old Jeanne Beaudoin of Montgomery Villiage, remained at the scene. Beaudoin was not injured.

For reasons that are still unclear, Guo was allegedly crossing Frederick Avenue when he was struck.

A collision reconstruction unit also responded to the scene. The southbound lanes of Md. 355 were closed for around four hours Thursday morning.
