The New Orleans police chief says investigators believe robbery was a motive in the weekend shooting death of a St. Louis man visiting the city to plan his wedding.

Police Chief Michael Harrison held a news conference Monday to discuss the death of 25-year-old Thomas Rolfes, a Tulane University graduate who was in the city with his fiancee to choose a wedding venue. He said injuries on Rolfes' hands indicated there may have been a struggle. Rolfes' body was found about 4:30 a.m. Saturday near a convenience store where surveillance video showed him buying two bottles of water an hour before. He earlier had been with friends at a bar nearly two miles away.

In a Facebook posting, former Republican Presidential candidate Mitt Romney said Rolfes, whose fiancee is from Boston, had worked in his 2012 campaign. Romney called the death "a senseless and tragic loss." ___
