Former American Idol contestant Alexis Cohen was killed in a hit-and-run this weekend in New Jersey, officials confirm.

Cohen, 25, was struck early Saturday morning in Seaside Heights. She was found around 4 a.m. by two passerby who called 911, Deputy Chief Michael Mohel of the Ocean County Prosecutor's Office tells the Morning Call newspaper of her hometown, Allentown, Penn.

She was pronounced dead at 6:35 a.m. at the Community Medical Center in Toms River, N.J. Autopsy results show she suffered chest, head and abdominal injuries, Mohel says.

Mohel says an investigation into the hit-and-run is ongoing.

Cohen auditioned for the seventh season in Philadelphia in 2007, but the show didn't air until January 2008. Idol cameras followed her to to her Allentown, Penn. studio apartment, which she shared with her mother, two cats and her dog.

"I march to the beat of a different drummer," admitted the memorable contestant. After Simon Cowell didn't vote her through to Hollywood, Cohen ranted he was "egotistical" and declared she was going into acting.

She later appeared on The View, Live With Regis and Kelly and Howard Stern's radio show.

Cohen unsuccessfully tried out again during Idol's eighth season.

American Idol Contestant Killed

Former American Idol contestant Alexis Cohen died early Saturday morning, the victim of a possible hit-and-run in Seaside Heights, N.J.

Cohen, 25, of Allentown, Pa., was found unresponsive on a street about 300 yards from where her car was parked in a lot, says Deputy Chief Michael Mohel of the Ocean County Prosecutor's Office.

First aid workers took her to Community Medical Center in Tom's River, where she was pronounced dead at 6:35 a.m., he says.

An autopsy performed Saturday afternoon by the office of the Ocean County Medical Examiner found multiple traumatic chest and abdominal injuries, and a closed head injury, Mohel says.

"There was evidence that her body was impacted by a vehicle," he says, noting the death is classified as a homicide.

Cohen, who auditioned for Idol in seasons 7 and 8, gained attention for her tirade against judge Simon Cowell, who rejected her performance.

No arrests have been made, says Mohel, who would not say where Cohen was prior to her death due to the ongoing investigation.
