‘Please help me’: 911 call details how on-duty cop shot ex-girlfriend — then killed himself

Michael DeMarco had his eyes on his ex-girlfriend as she walked her dog Thursday morning in the Inlet Harbor Club neighborhood of Boynton Beach.

The Palm Beach County Sheriff’s deputy was on duty and in uniform, sitting in his patrol car, as the woman got within reach.

“We can confirm that DeMarco was dressed in a [Palm Beach Sheriff’s Office] uniform consisting of khaki pants and a black embroidered shirt at the time of the shooting,” said Stephanie Slater, a Boynton Beach police spokeswoman.

DeMarco waited until she neared the garage door. Then, he shot her and turned his county-issued gun on himself, according to 911 calls released by Boynton Beach police Monday.

The couple dated for about five months before breaking up about three weeks ago, deputies said.

The woman, whose name has still not been released, is in critical but stable condition after being shot several times.

Officials say the case is being treated as an attempted-murder/suicide. DeMarco died on the scene.

In the 911 recording, the woman could be heard softly pleading. “Please help me,” she told a 911 operator.

The case is under investigation.

According to the Palm Beach Post, DeMarco, divorced since 2002, had worked in law enforcement since at least 1987, when he started with the Lake Worth Police Department. He began working for the Palm Beach County Sheriff’s Office in 1995 and most recently worked as a detective in the civil-process department.

DeMarco had been a volunteer football coach and was active in youth football leagues in the Boynton Beach and Wellington areas, according to reports.
