(WMC-TV) Union County, Desoto County, the FBI, and US Marshals set up a command post in Alpine, MS for what is now being called a manhunt for 35-year-old Adam Mayes.
"We feel like now that we may have enough evidence to go on the manhunt," said Union County Sheriff Jimmy Edwards.
Sheriff Edwards says the search is now on in Northeast Mississippi for Adam Mayes, the man investigators believe is responsible for the disappearance of Jo Ann Bain and her three daughters, 14-year-old Adrienne, 12-year-old Alexandria, and 8-year-old Kyliyah Bain.
"We believe he is extremely dangerous," stated Edwards.
Mayes was considered a friend of the family.
Nearly 90 miles from where the family was last seen at their home in Hardeman County, TN, a break in the case came when the FBI announced developments in Alpine, MS on Saturday.
"We started Friday morning conducting search warrants when we found out that this person was in our county from Hardeman, TN. He lived here, his family lived here, and of course we ended up recovering two bodies," said Edwards.
The Union County Sheriff confirmed that the bodies were found behind the home of Adam Mayes' parents in Guntown, MS. He would not release further details, but did say the bodies were found in a shallow grave.
"They've been everywhere, they've done a really great job," said Alpine Resident Kayla King.
Residents in the area say the thought that Mayes could be in their community has left them restless.
"It's scary and I'm scared to stay by myself at night and that's bad, you can't even go outside your own home," said King.
"We'll stay in this area until it's over to try to work and make sure that it's safe and if something happens we'll be close and be right on top of it," stated Sheriff Edwards.
Amber Alerts have been issued for the Bain daughters. At one point, the mother was considered a suspect in this case, and she is no longer listed on the Amber Alert.
The FBI is offering a $50,000 reward for tips leading to the arrest of Adam Mayes. Anyone with information is urged to call 1-800-TBI-FIND.
