A Virginia State Police trooper was seriously injured in a car crash that happened as the trooper was responding to the scene of a separate car crash involving another state trooper on I-395.

Around 10:15 p.m., Trooper R.C. Weeks was listening to the police radio and heard that Trooper B.J. Sisk had been in an accident and needed assistance, according to police spokeswoman Corinne Geller. Weeks immediately responded, and as he was coming around the ramp from Route 644 west to I-395 south, the patrol vehicle ran off the road, spun out, and struck the jersey wall, Geller said.

.Weeks suffered serious injuries that were not life-threatening in the single-car crash and is recovering at Inova Hospital.

The trooper involved in the first crash, B.J. Sisk, had been heading headed south on I-395 with flashing lights on, headed to an emergency call. Suddenly a Lincoln Town Car in front of him in the left lane stopped, Geller said.

Trooper Sisk immediately hit the brakes, but seconds later a driver in an Acura GL rear-ended his patrol car at about 65 mph, pushing the state trooper’s car into the Lincoln Town Car, Geller said.

Trooper Sisk and the drivers of the Lincoln and Acura cars, who were all wearing seat belts, were treated for minor injuries at Fairfax Inova Hospital.

Fahim Javed, 30, of Springfield, the driver of the Lincoln Town Car that stopped suddenly in front of the trooper, was charged with reckless driving.

The driver of the Acura, Eric F. Balangue, 35, of Woodbridge, who rear-ended the trooper’s car and according to police could not stop in time, also was charged with reckless driving.

Geller said, both crashes remain under investigation.
