Arkansas law enforcement agencies have begun an investigation into the unsolved killings of as many as 15 people, the Faulkner County sheriff's office said Thursday.
Sheriff Karl Byrd told reporters an informant provided information as Jacksonville police in Pulaski County found the remains of one body based on a tip that two bodies were dumped near Jacksonville.
Byrd would not comment further, saying the investigation was "in a very sensitive stage." He said he could not confirm that the informant was an inmate as initially reported in the media. However, the informant was being carefully guarded, he said.
Sheriff's Maj. Andy Shock said the investigation involves Arkansas' neighboring states, although he would not say which ones.
Besides the sheriff's office and the Jacksonville police, the Arkansas State Police, the FBI and the Pulaski County Sheriff's Office are involved, Shock said.
