A Pennsylvania man is in critical condition after his car overturned into an Ellicott City pond on Monday afternoon, Howard County police say. The driver had been involved in two hit-and-run incidents just minutes before the crash.

The first incident occurred on I-70 as the driver, Brendan N. Langhauser, 38, was driving westbound. Langhauser’s Ford Edge first struck a 75-year-old woman at around 1:30 p.m. when he stopped his vehicle in the driving lane and reversed into her SUV, according to witnesses. The woman was not injured.

The second incident was reported just moment after when Langhauser drove away from the scene of the first incident and drove southbound on Route 29. Witnesses say that Langhauser sideswiped a Ford van in an adjacent lane. The other driver, 33, was not injured.

After the second incident, Langhauser was seen exiting onto Route 100 eastbound and driving at a high speed. Witnesses then say that the car drifted to the right side and struck the guardrail before overturning into the pond.

Langhauser was pulled from the water by the Howard County fire department and administered first aid. He was transferred to Shock Trauma at the Howard County General Hospital.

The crash is currently under investigation. Police say they believe speed was a factor in the crash and are investigating to determine whether or not Langhauser was under the influence of drugs or alcohol.
