ATLANTIC CITY – A man was shot in the head Saturday afternoon at the Stanley Holmes Village apartment complex in Atlantic City, police said.

Police spokeswoman Monica McMenamin said the victim sustained a single gunshot wound to the head around 1:23 p.m. Saturday and was taken to AtlantiCare Regional Medical Center, City Campus. The victim was admitted for surgery, but police said he is expected to survive his injuries.

The shooting occurred about a quarter-mile from Atlantic City's Second Baptist Church, which on Saturday was conducting the second day of a two-day guns-for-cash buy-back program to stem gun violence.

Responding officers found the victim lying on the ground and bleeding from the head on the 1600 block of City Place.

Police called for backup from neighboring municipalities after a crowd gathered at the scene of the shooting, Atlantic City police Lt. Ed Brady said in a statement.

“While attempting to assist the victim and secure the crime scene, responding officers were greeted by a large, unruly crowd,” Brady said.

According to scanner audio posted on the blog Atlantic City 911 on Saturday, a responding officer tells the dispatcher: “The crowd's getting bad, get me some units. They're fighting one of our officers down here.”

The dispatcher is heard asking neighboring police departments to dispatch a K-9 unit.

A heavy police presence converged at about 1:45 p.m. at Martin Luther King Boulevard and City Place. Police appeared to be marking evidence on City Place, an alley in the center of the housing development. Police officers from Atlantic City, Egg Harbor Township, Longport, Pleasantville and Ventnor responded.

The victim Saturday was found about 40 feet from a memorial to Derreck Mack, 18, who was shot and killed by police Dec. 17 after he allegedly pulled a .45-caliber handgun on officers. Police said he and another suspect allegedly armed with a .9 millimeter handgun were fleeing from officers.

A memorial to Mack around a nearby utility pole still had several dozen stuffed animals and artificial flowers. Neighbors in December protested the police shooting as a use of excessive force. That shooting remains under investigation.

Lead investigator Det.David Smith and other detectives canvassed the neighborhood Saturday for witnesses and evidence.

The apartment complex has been the scene of several violent crimes in recent years, including the fatal shooting of apartment resident Jose Ortiz, 59, on Sept. 6 as he rode his bicycle through a courtyard. The Atlantic City Housing Authority in a grant application last year called Stanley Holmes Village the agency’s “most troubled” housing project.

Passersby were distraught that the Stanley Holmes Village complex appeared to be the scene of yet another shooting.

“Crazy,” said Norman Hayes, 55, of Atlantic City, wearing a suit as he stood on the median in the middle of Dr. Martin Luther King Jr. Boulevard.

A short time after the shooting, at about 2 p.m., police appeared to be executing a search warrant at a home on City Place. Police diverted traffic from nearby roads for a short time while they investigated the scene.

All roads reopened by 2:30 p.m.

Police are asking anyone with information about the shooting to contact the Atlantic City Police Department Criminal Investigations Unit at 609-347-5766. Information also can be sent by text anonymously to TIP411 or called into Crimestoppers at 609-652-1234.
