Sheriff Dennis Meeks made the request for assistance after officers found 40-year-old Robert Gene Yingst dead in his cell Wednesday afternoon.
Yingst, a Florala resident, was placed in a cell Monday, April 19 after being arrested on kidnapping and sexual assault charges. Officers found him dead two days later.
A cause of death has not been released, and no other information was made available pending an ongoing investigation.
The ABI's investigation, once completed, will be turned over to the Covington County Sheriff's Department and the District Attorney's office.
