NEW BRUNSWICK, N.J. — Prosecutors say a Rutgers University student has died after she “became distressed” while attending a small gathering at a fraternity house.

A preliminary investigation determined that the death of 19-year-old Caitlyn Kovacs may be alcohol-related. But the cause of death has not yet been determined.

Middlesex County prosecutors say the South Brunswick resident was a sophomore at the university.

They said Kovacs was at the Delta Kappa Epsilon fraternity house in New Brunswick when she appeared to be in distress around 3 a.m. Sunday. Some friends took her to the hospital, where she was pronounced dead a short time later.

Hospital officials notified police about the death, which is under investigation by the prosecutor’s office and the Rutgers and New Brunswick police departments.
