HARTFORD, Conn. (AP) — A Connecticut State Police trooper under investigation for his role in a car crash involving his state vehicle that severely injured two women has been suspended.

Brian Foley, spokesman for state police Commissioner James Rovella, said the paid suspension for Sgt. John McDonald announced Thursday is directly related to the investigation of the Sept. 25 crash in Southbury.

Police are investigating whether McDonald had been drinking at a retirement party at a brew pub for another trooper before the accident.

The crash injured Lisa Conroy, of Middlebury, and her 19-year-old daughter, Madison. They have sued McDonald, the bar and state police. McDonald was also injured in the crash and wasn’t given a sobriety test because he had to be taken to a hospital.
