NEW ORLEANS -- The body of missing Atlanta Gas Light executive Douglas Schantz was found in the Mississippi River Tuesday, four days after surveillance video caught him stumbling up the narrow gangplank of a docked riverboat.

The Texas man was last seen leaving a French Quarter bar last week.Schantz, 54, disappeared early Friday morning after making a $25,000 scholarship donation to Tulane University, the school his daughter was attending.

The search for Schantz began on Bourbon Street where he had been drinking with colleagues until the early morning hours, and followed surveillance cameras as he headed toward the Mississippi River.

Schantz's 25-year-old son Michael Schantz has seen one of several videos that caught his father walking towards the riverboat Natchez.

"Of course I am hoping for the best, and if a miracle happened it would happen to him because of everything he's done for the community," said 25-year-old Michael Schantz shortly before his father's body was identified. "But I've accepted the fact that I might have to take over for the family."
