A Houston energy executive has vanished in New Orleans after visiting a Bourbon Street bar, MyFoxDFW.com reports.

Doug Schantz, 54, disappeared Friday at around 2 a.m. after leaving the bar. New Orleans police report his credit cards and ATM card have not been used, making them suspect foul play.

Schantz is the president of Sequent Energy Management in downtown Houston. He was visiting New Orleans to make a donation to his daughter's university, MyFoxDFW.com reports.

Peter Tumminello, the executive vice president of Sequent, has taken over as acting president of Sequent, FoxBusiness.com reports.

"We are deeply concerned about Doug, and personnel from AGL Resources and Sequent have been working around the clock with law enforcement agencies to determine Doug's whereabouts," John Somerhalder II, AGL’s CEO, said in a statement.

Schantz's son Michael has gone into the streets, handing out flyers in the historic French Quarter of New Orleans hoping for a break in the case.

“He’s just a great man, loves the people he works with, loves his wife, and you know my mom, his wife is very upset, just heartbroken,” Michael Schantz told MyFoxDFW.com.

Greater New Orleans Crimestoppers is offering a $5,000 reward while Sequent Energy Management is matching that amount.
