Fairfax County prosecutors are considering charges against Board of Supervisors Chairman Gerald E. Connolly (D) after he was involved in a fender-bender at Tysons Corner last week and then drove away, Fairfax police said yesterday.

The incident occurred about 10:50 a.m. Friday near International Drive and Route 123, and police and Connolly related identical versions: that Connolly was driving his 2003 Toyota Camry in one of the two left-hand turn lanes on International Drive and began to move into the other turn lane when his car stalled. Police said a 2003 Ford Explorer driven by Lewis M. Pfister of Ashburn collided with Connolly's Camry while its nose was in the Explorer's turn lane.

Connolly said he heard the Explorer's brakes squeal and horn honk, but "I felt no impact and heard no noise." He restarted his car and drove off. "I would never, ever leave the scene of an accident under any circumstances," Connolly said.

Pfister did not return calls seeking comment.

Connolly's Camry had a noticeable dent to the left front panel near the left tire, and police estimated the damage at $200. The damage to Pfister's Explorer was $300, Connolly said police told him. An officer visited his home Saturday morning to investigate. That's when Connolly said he realized that his car and the Explorer had actually collided. He said he was stunned.

Connolly said he urged the police to handle the incident "as they would any other case." The chairman said he also called Pfister but got no response. Fairfax police spokeswoman Mary Ann Jennings said the case had been referred to the commonwealth's attorney's office for possible charges.

Gerald E. Connolly said he was unaware of the accident.
