HOUSTON -- A body found in the Mississippi River Tuesday is that of a Houston energy executive who disappeared during a trip to New Orleans, KPRC Local 2 reported.

Douglas Schantz, 54, was the president of Sequent Energy Management. He had last been seen alive at a bar on Bourbon Street at about 2 a.m. Friday.

New Orleans police began focusing on the river after tracing Schantz's route there from a Bourbon Street bar. Police searched videos from businesses in the French Quarter were able to place Schantz at the dock for the Riverboat Natchez at about 2:40 a.m. on Friday.

His body was found near the spot where he was last seen on surveillance video, officials said.

"He had all his credit cards, his jewelry was on him," said Bob Young of the New Orleans police department. "At this time we feel it was accidental."

Police Superintendent Warren Riley said Schantz, who had been drinking, seemed disoriented on the videos. He is seen going into a restricted area and is not seen again on the video, despite a review of the following four hours of tape, Riley said.

"At no point in that 36 minutes was he ever approached or accompanied by any individual," Riley said.

Schantz was in New Orleans to see his daughter, who is a senior at Tulane University. He, along with some of his co-workers, donated a check of $25,000 to the school while in the city.

Schantz's wife reported him missing after he didn't meet his daughter for a flight home.
