WILDWOOD CREST — Lt. Joseph McGrath has been named officer in charge of the Wildwood Crest Police Department effective immediately, Mayor Carl Groon said Wednesday afternoon.

“I expect this to be through the summer,” Groon said.

The department was previously headed by Capt. David Mayer, who was designated officer in charge after the Dec. 31, 2013, retirement of Chief Thomas DePaul.

Groon would not comment on Mayer’s current status except to say that Mayer was still employed by the department.

In a letter dated April 23, Cape May County Prosecutor Robert Taylor said he was assigning Detective Mark Weeks, a retired major from the State Police, to be “a monitor of the Wildwood Crest Police Department during the transition to the new leadership in the department.”

Weeks will oversee the department in consultation with McGrath, Taylor said, while McGrath will be in charge of the department’s day-to-day operations.

“He will be available to you as Director of Public Safety,” Taylor wrote to Groon.

Taylor then directed the letter be posted in the department’s headquarters so the staff was aware of what had happened.

The Prosecutor’s Office was brought in early this year by Groon to conduct what Groon called a long-term review of the 23-member department.

DePaul said in January that “there is an investigation going on there, an internal investigation,” but no details of that investigation have been released so far.

In January, Mayer said he couldn't comment on the investigation, but he said the Prosecutor’s Office was “more or less a liaison if any issues come up pertaining to the investigation.”

Taylor said Wednesday that he had “no comment on any investigation.”

He added that the borough’s residents should not notice any change in service.

“This is a pretty normal process. We’ve done it before in other municipalities,” Taylor said, adding the monitor would be in place at least until the fall.
