Wiggins was a person of interest in the case after police found she was "associated" with one of the suspects up to the day of the murders. After police questioned her, Wiggins was charged with accessory after the fact of a felony murder and was released after she posted $10,000 bail. If convicted, she faces a maximum sentence of 30 years in prison, state attorney Bill Eddins said.
Morgan, in referring to Wiggins' release on $10,000 bail, said she is "absolutely" not a threat to society.
Wiggins was oringally arrested in connection to the case when she was found on her yacht, the Classy Lady, in Alabama. She also owns a dozen properties in three states and a Rolls Royce.
Last month, police recovered several weapons including the probable "murder weapon or weapons." It was not immediately clear from where investigators recovered the weapons. Police have enlisted the help of the federal Alcohol, Tobacco and Firearms to test the weapons for prints, DNA, blood splatters and ballistics, Morgan said.
Morgan confirmed reports that the Drug Enforcement Agency was helping in the investigation, but he refused to spell out their role other than to say the DEA was investigating the suspects.
"Look at it from a broad perspective," DEA spokesman David Melenkevitz told ABCNews.com. For the sheriff's office to call in the DEA, "There has to be some drug connection somewhere."
Melenkevitz would not elaborate on the DEA's investigation.
