ABERDEEN TOWNSHIP, N.J. (AP) _ A woman attending her high school prom gave birth in a restroom, left the baby in a trash can and returned to the dance floor with her boyfriend, authorities said.

Chaperones and medics tried to resuscitate the full-term baby but it was pronounced dead at a hospital.

The baby was found Friday night by a maintenance worker who had been told there was blood on the floor of one toilet stall, said Monmouth County prosecutor John Kaye.

The worker found blood splattered on the walls, toilet and floor, and the trash can containing the baby's body was inside the stall.

Autopsy results were to be released Monday, Kaye told the Asbury Park Press. He said he was told the baby was a boy.

``We're treating it as a potential homicide,'' he said. ``In a case like this, the issue tends to be whether this was a stillborn baby or a live birth.''

After giving birth, Kaye said, the 19-year-old woman returned to the ballroom at the Garden Manor catering hall, danced with her boyfriend and even requested a song from the band at the prom for Lacey Township High School.

After police identified her as the mother, the woman was taken to Bayshore Community Hospital in Holmdel, Kaye said. The woman, whose name was not released, remained hospitalized Sunday.

Authorities would not say how she was identified as the mother of the 6-pound, 6-ounce, 19-inch baby.
