However, they did say the death of 59-year-old Ronald Bowman is still being treated as a homicide, especially since his body was found with his hands bound.
The medical examiner is awaiting further test results as this investigation moves forward.
Bowman was supposed to attend a school-related function on Saturday night but, when he didn't show up, a family member went looking for him and discovered his body.
Bowman's brother-in-law, Vincent Hart, said he hadn't been since at least Thursday - even missing his grandson's football game.
"He picks him up every Friday," Hart said. "He didn't show up at the game."
Immediately, a Facebook page page was set up dedicated to Bowman's memory. Friends posted prayers and pleas that police can quickly figure out how exactly Bowman died and, if it was murder, quickly bring to justice whoever is responsible.
"This shouldn't have happened to him," said friend Reatha Stocks.
