An elderly man was fatally struck by a car in Anne Arundel County while walking down the road Monday evening.

Police said that Nelson Bert Lehnert, 77, apparently stepped off the curb into the roadway on Baltimore Annapolis Boulevard in Linthicum, Md., around 5:15 p.m. Lehnert was struck by a vehicle in the right lane driven by 69-year-old Richard Charles Snyder Sr..

Lehnert was transported to the University of Maryland Hospital Shock Trauma Center with what were initially believed to be survivable injuries. However, once at the hospital, Lehnert’s condition deteriorated, and he was pronounced dead around 9 p.m.

According to investigators, neither alcohol nor speed appear to be factors in the accident. Investigators said “pedestrian error” appears to be the primary cause.

“Mr. Snyder was unable to avoid the collision with Lehnert,” police said in a news release.

The investigation is ongoing.
