A man in his early 20s was stabbed to death this morning in Jersey City, authorities have confirmed.

Shortly before 4 a.m., Jersey City police received a call of a stabbing in the area of 46-48 Manhattan Ave. between Central and Sherman avenues in the Heights, according to Gene Rubino, spokesman for the Hudson County Prosecutor's Office.

By the time cops arrived, EMS was already on the scene working on the man who was stabbed.

The man was transported to the Jersey City Medical Center and was later pronounced dead, Rubino said.

The Hudson County Prosecutor's Office is investigating the death.

Rubino did not release any other information.

According to police radio transmissions, the man was stabbed at least twice in the abdomen.

The transmissions also indicate that a person suspected of committing the stabbing walked into Christ Hospital on Palisade Avenue to receive treatment for injuries.

A man who lives on the block told Journal staff writer Julie Kayzerman today that he and his wife saw the man on the ground and tried to save his life by applying pressure to the two places the man had been stabbed in his stomach.

The man was still alive when EMS took him away, the resident said.

Another resident told Kayzerman the man was attacked by a group.

Several residents told Kayzerman that their neighborhood is normally very quiet and safe and this incident was unusual.

Wilmur Flores, 46, lives across the street and woke up to sirens at around 3:30 a.m.

"This is a quiet neighborhood," Flores said. "This is the first time I heard something like this happen here. Now I'm scared."

This is the 18th homicide in Jersey City this year, following the killing of a Joshua Taylor, 20, who was shot and killed on Kennedy Boulevard near Lexington Avenue on Friday, Aug. 8.
