'A student at Rider University's Westminster Choir College has been charged over a fellow student's death, prosecutors said Thursday.

According to the Mercer County Prosecutor's Office, 19-year-old Kieran Hunt of Piscataway sold heroin to freshman Justin Warfield and shot it up with him in the Princeton music school's parking lot on Tuesday evening.

Prosecutors said Warfield, an 18-year-old from Columbia, Md., had to be taken by ambulance early Wednesday to University Hospital in Princeton, where he was pronounced dead.

Hunt was arrested and charged Wednesday with being liable for Warfield's drug death, as well as selling him the heroin, prosecutors said. He is free on $100,000 bail.

Mercer County Prosecutor's Office spokeswoman Casey DeBlasio didn't immediately respond to an Associated Press e-mail sent to him Thursday; no phone listing was found for Hunt in Piscataway.

Warfield's death comes seven months after another Rider freshman, Gary DeVercelly Jr., died after drinking at a fraternity party on the school's main campus in Lawrenceville.

The case got widespread attention, partly because of the legal maneuvering that followed.

Three students were charged with aggravated hazing, as were two university officials. The charges against the administrators were dropped; two of the students were accepted into a program that could allow them to avoid prison time; charges against the third student are still pending.

The case prompted the university to establish strict new rules governing on-campus alcohol use.

People who knew Warfield back in Maryland told The Star-Ledger of Newark that he graduated in June from Wilde Lake High School in Columbia, which is located between Baltimore and Washington. A drummer, he was a member of "The Getaways," a band that performed at venues in that area.

Steve Holmes, director of the Maryland State Boychoir that Warfield was part of, remembered a talented young man.

"He was very charismatic. Justin had a shimmering beautiful voice..."'
