A Millville man was stabbed to death in Ventnor on Sunday afternoon, marking first homicide in the city in four years.

Police responded to a 911 call on the 300 block of North Wissahickon Avenue about noon and found the man outside and unresponsive, according to a statement from the Atlantic County Prosecutor’s Office.

The man’s identity was not released Sunday night pending notification of his family.

Paul Cramer, who lives a few doors down from where the incident occurred, said he had no idea anything was wrong until police approached his home in the afternoon to section off the area with crime-scene tape. By that time, the victim appeared to be gone and several police cars lined the street, he said.

“I never heard anything,” Cramer said. “I went outside and asked what’s going on, and the police just said, 'This is a police investigation.'"

Cramer, who has lived in the neighborhood for four years, described the area as safe and said many elderly residents walk their dogs outside at night. He also described a group of younger people who recently had been spending time in one of the houses on the street.

“They were a little suspicious, frankly, just the way they’d come and go,” he said. “Aside from that, it’s a very quiet neighborhood.”

This is the 24th homicide in Atlantic County this year — the most since 2009, when 27 people were killed.

Steven Wingard, 47, was the victim of Ventnor’s last homicide, on Nov. 4, 2008. He was found fatally stabbed inside his South Hillside Avenue apartment when police went to check on him. He had stab wounds to his neck.

In June 2009, Juan Carlos Lenis Montoya was sentenced to eight years in prison after pleading guilty to manslaughter in the Wingard's killing.

As of 5:30 p.m. Sunday, police still had cordoned off several homes on Wissahickon at Balfour Avenue, and three city police vehicles were present. Police at the scene would not provide any information.

Wissahickon Avenue has homes only on the west side of the street and borders a marsh. The location is about five blocks away from the Ventnor Educational Community Complex.

Mayor Mike Bagnell confirmed an investigation was under way but said he did not know any further details.

The Atlantic County Prosecutor’s Office Major Crimes Unit and the Ventnor Police Department are investigating the homicide.

Anyone with information is asked to call the Major Crimes Unit at 609-909-7666 or Ventnor police at 609-822-2101.
