PALM BEACH GARDENS, Fla. (WFLA) — Palm Beach Gardens police announced the arrest of a Florida man who beat another man with a golf club and drowned him “forcibly” underwater.

Junior Boucher, 36, of Loxahatchee, was charged with first-degree murder for the death of 65-year-old Brian Hiltebeitel.

On Monday, police said Boucher attacked the man with the victim’s golf clubs at the Sandhill Crane Golf Club, located in the 11000 block of Northlake Boulevard before drowning him in a nearby pond.

According to an arrest report obtained by NBC affiliate WPTV, a witness told police he heard a man yelling and saw Hiltebeitel “retreating” from Boucher, who was swinging a golf club at him. Hiltebeitel reportedly screamed several times, “he’s trying to kill me.”

The report said both men fell to the ground and Boucher began chasing Hiltebeitel, repeatedly hitting him with the club. When they reached the pond, Boucher reportedly jumped onto him and “appeared to be choking him.”

The witness added that when Boucher got off Hiltebeitel, he was no longer moving.

Officers arrived around 1:30 p.m. to find Hiltebeitel’s body in the pond next to hole one on the golf course. They said he suffered “deep lacerations to the back of his head” and was pronounced dead at the scene.

The arrest report also said Boucher, who was found unclothed, ran away and refused to stop and entered murky waters. This prompted police to use an “electronic control weapon,” to take him into custody.

“This appears to be a random act of violence,” police said in Tuesday’s press conference.

At 12:30 p.m., roughly an hour before the fatal incident, Boucher was reported missing by the Palm Beach County Sheriff’s Office. It was revealed that Boucher also has a lengthy criminal history involving drug possession, domestic battery, and fleeing and eluding law enforcement, among others.

WPTV reported that a judge denied Boucher bond on Tuesday before he claimed his name is actually Manuel Acosta Rodriguez.

This remains an ongoing investigation.
