A 35-year old Falls Church man who reportedly refused medical treatment after his car collided with another vehicle yesterday in Arlington died a few hours later, after colliding with two other cars in McLean.

Fairfax County police described the episode as unusual and said an autopsy will be conducted to determine whether the first incident may have contributed to the death.

The victim was identified as Issan Saleh, of 7308 Idylwood Court. He was pronounced dead at the scene of the second accident, which occurred on Westmoreland Street at about 5:20 p.m.

In the first accident, U.S. Park Police said, Saleh was driving south on the George Washington Memorial Parkway near Spout Run at about 3:30 p.m. when his car was struck by a second vehicle and left the road, striking a bridge abutment.

The other car drove away and could not be located, Park Police said.

About two hours later, Saleh, who according to Fairfax County police had refused medical attention following the parkway collision, was headed east on Westmoreland Street, near McLean High School.

Police said that an 18-year old McLean youth, driving west in another vehicle on Westmoreland, attempted to make a left turn onto Davidson Road and the two cars collided.

Saleh's car spun around, according to police, and collided with a third car, which had been behind him. The driver of that car, identified as Carlos R. Escudero, 35, of 1921 Relda Ct., Falls Church, was taken to Fairfax Hospital, where he was listed in critical condition.
