Toxicology results showed that Cohen was drinking alcohol before she died, according to the N.J. Medical Examiner’s Office. Further investigation revealed that Cohen had spent the evening before she died at several bars and clubs, authorities said.
Cohen's death was the result of vehicular homicide, Cops said.
A 23-year-old man was arrested in connection to the death of Cohen, who was found dead on the side of the road in the Ocean County shore town. Daniel Bark, 23, of Toms River, N.J., was arrested on charges of reckless driving and leaving the scene of an accident -- charges that could land him in jail for 10 to 15 years if convicted.

The charges against Bark won’t be impacted by the toxicology report, Deputy Chief Michael Mohel of the Ocean County Prosecutors Office said Wednesday.
An autopsy indicated that Cohen suffered chest, head and abdominal injuries caused by the collision, Mohel said days after the crash.
A passing driver noticed Cohen and called 911. Emergency workers rushed her to a nearby hospital, but it was too late.
