A man whose body was found floating in the Mullica River in Burlington County on Saturday has been identified as John Kohlbecker, 26, of Philadelphia, police said Tuesday.

Kohlbecker's body was spotted by two fishermen near Hog Island in Washington Township, and pulled out of the river by New Jersey state troopers.

Trooper Lawrence Peele, a police spokesman, said the cause of death was drowning and hypothermia. The state police's major-crime unit will determine whether any foul play was involved, Peele said.

The last sighting of Kohlbecker was believed to be at 9:30 p.m. on Feb. 11, when he was stopped for a traffic violation by local police in Buena Borough, Atlantic County, state police have said.

On Feb. 14, his 1995 white Toyota Camry was found at the Green Bank State Forest Station in Wharton State Forest in Washington Township, police have said. He was reported missing that day.

The next day, state police reported that detectives found stained clothing on the banks of the Mullica River and sent the items to a lab for analysis. Peele said it was too early to speculate on what those stains were.
