A body found floating in the Pearl River north of Monticello Saturday is believed to be that of Dau Mabil, a 33-year-old Belhaven man last seen in March.

Thursday, a judge issued an order prohibiting burial or cremation until the state can conduct an autopsy.

Karissa Bowley, Mabil’s wife, said in March that her husband had last been seen March 25, when he left his Belhaven Heights home in Jackson to go for a walk. Bowley said he left his cell phone at home, but that was not unusual.

“People have been looking for him, but he’s not alive,” said Mabil’s brother, Bul Garang Mabil. “He’s not. He’s not alive. I believe the body that was found is my brother, Dau. Let the public know.”

Attorneys said evidence exists, including video, that the last place Mabil was seen alive was on the Museum Trail in Jackson, where attorney Lisa Ross said he fought for his life. Ross represents Mabil’s brother and son.

“We want to make sure that whoever harmed Dau is brought to justice,” said Ross.

U.S. Rep. Bennie Thompson has called on the U.S. Department of Justice to investigate.

Anyone with information is asked to report it to law enforcement.
