WOODBURY -- A Franklin Township woman has been sentenced to more than seven years in prison for her fourth drunk driving conviction where three Rowan University students were hit crossing the street, authorities said.

Judge Robert P. Becker handed down the 90-month sentence to Kelli D. Hennessey in Gloucester County Superior Court Friday for her collision in a Glassboro school zone on Nov. 6, 2011.

"We are pleased the Court agreed that this individual posed a danger to the driving public and pedestrians and needed to be kept off our streets," Gloucester County Prosecutor Sean F. Dalton said in a release.

The 31-year-old was convicted on three counts by assault by auto in July, where she testified that an acquaintance was driving her car and fled after the crash. However, an officer's testimony from the scene contradicted her statements.

During Hennessey's sentencing Friday, prosecutors said they read a letter from one of the students injured in the crash, who wrote the collision has left her fearful of driving.

The student fractured her collarbone, broke her leg, which had to be reinforced with a metal rod and screws, and still suffers from a blood clot, according to the release. The two other students suffered leg injuries.

Hennessey was also sentenced to 180 days in prison for drunk driving.
