Police questioned two women Thursday in connection with a series of slayings of middle-age male motorists in north Florida and south Georgia, but released them six hours later.

"There is no reason to believe they had any connection with the murders," said Asa Higgs, a spokesman for the Jacksonville Sheriff's Office.Police Sgt. Steve Weintraub said earlier the two women were picked up because they "matched the descriptions somewhat."

All of the eight known victims were white, roughly between the ages of 40 and 60. All were shot, some repeatedly. Some were stripped naked and robbed, their bodies dumped along rural roads. Two other men remain missing.
