Well, they found their dismembered bodies in a river. All 4 corpses also had gunshot wounds.
Sounds like they were planning some type of robbery and the "victim(s)" got the jump on them.
And they were on bicycles?
Police Chief Joe Prentice on Monday confirmed the bodies of four men pulled from the Deep Fork River, southeast of the city of Okmulgee, belonged to Mark Chastain, 32; Billy Chastain, 30; Alex Stephens, 29; and Mike Sparks, 32, who were reported missing overnight last Monday.
The men, close friends, were believed to have left Billy Chastain's home in Okmulgee on Sunday night, reportedly on bicycles, according to police.
Investigators believe that the men planned to commit some kind of criminal act when they left a residence, according to a witness who told police they were invited to go with the men to "hit a lick big enough for all of them," Prentice said.
^^^ "Foul play is suspected."
