(CBS/AP) JACKSON, Miss.- A 22-year-old man was charged with murder Thursday in the death of a mayoral candidate in the Mississippi Delta.
The Coahoma County Sheriff's Department said in a news release that Lawrence Reed of Shelby was charged in the death of Marco McMillian. McMillian, 34, was a candidate for mayor of Clarksdale and was well-known in the community and beyond.
McMillian's body was found near the Mississippi River levee Wednesday morning between Sherard and Rena Lara, Coahoma County Coroner Scotty Meredith has said.
The body was sent for an autopsy, and the cause of death hasn't been made public.
"There's a lot of people upset about it," said 33-year-old Dennis Thomas, who works at Abe's Barbeque.
"Why would somebody want to do something like that to somebody of that caliber? He was a highly-respected person in town," Thomas said.
McMillian, a Democrat, wasn't running what many would consider a typical campaign for political office in Mississippi, which is known for its conservative politics. Campaign spokesman Jarod Keith said McMillian's campaign was noteworthy because he may have been the first openly gay man to be a viable candidate for public office in the state.
McMillian, who was black, also forged ties while serving for four years as international executive director of the historically black Phi Beta Sigma Fraternity Inc. Photos on McMillian's website and Facebook page show him with a younger Barack Obama, former President Bill Clinton and with U.S. Rep. John Lewis, a Georgia Democrat.
In addition to his role at the fraternity from 2007 to 2011, McMillian previously worked to raise funds as executive assistant to the president at Alabama A&M University and as assistant to the vice president at Jackson State University, according to his campaign. He was also CEO of MWM & Associates, described on its website as a consulting firm for nonprofit organizations.
A statement from the fraternity said he secured the first federal contract to raise awareness about the impact of HIV and AIDS on communities of color. It noted that Ebony Magazine had recognized him in 2004 as one of the nation's "30 up-and-coming African Americans" under age 30.
McMillian is a 1997 graduate of Clarksdale High School who graduated magna cum laude from Jackson State and held a master's degree from St. Mary's University in Minnesota in philanthropy and development. His supporters said he had big ideas for Clarksdale, a town of about 17,800 people.
He was hoping to win the office being vacated by Mayor Henry Espy Jr., the brother of Mike Espy, a former congressman and U.S. agriculture secretary. Henry Espy decided not to seek re-election after more than two decades in office. Espy's son, state Rep. Chuck Espy, and Bill Luckett, a partner in Freeman's club, were among the other well-known candidates in the race. The primary is May 7, 2013.
The Gay & Lesbian Victory Fund and Institute tweeted: "Our hearts go out to the family and friends of Marco McMillian, one of the 1st viable openly (hash)LGBT candidates in Mississippi."
McMillian's campaign said in a statement that words cannot describe "our grief at the loss of our dear friend."
"We remember Marco as a bold and passionate public servant, whose faith informed every aspect of his life," the statement said.
Clarksdale is well known to blues fans as the home of the crossroads, where Robert Johnson is said to have sold his soul to the devil for skills with a guitar. Academy Award-winning actor and Mississippi native Morgan Freeman is part owner of the Ground Zero Blues Club in town. Clarksdale also is hounded by the poverty typical of the Mississippi Delta.
