One person was killed and 13 were injured, three of them critically, in two multiple-car accidents in Ocean City less than an hour apart, police said yesterday.

The more serious accident occurred shortly after 10 p.m. Friday and involved a pedestrian and four automobiles.

Nicholas Evers, 18, of Highland, was crossing Coastal Highway in front of the Gold Coast Mall when he was struck and fatally injured by a northbound vehicle, Officer Jay Hancock said.

After striking Evers, the car rammed into another in the left-turn lane that, in turn, hit a third vehicle. The second car then crossed the highway divider and collided with a southbound car, police said.

Lisa Truskowski, 21, the driver of the first auto, and a passenger, Mark Cecil, 22, both of South Laurel, were pinned inside their car for about an hour before being freed, Hancock said. Both were reported in critical condition yesterday at Peninsula General Hospital in Salisbury.

Also critically injured was the driver of the last car struck, Michael Nolan, 55, of Silver Spring, police said. He also was at Peninsula General.

Five others were injured in the accident, none seriously, Hancock said, adding that a Delaware State Police Med-Evac unit had to be summoned.

In an accident 45 minutes earlier on 120th Street involving two cars, five people were injured, Hancock said. One was admitted to Peninsula General and the others were treated and discharged.
