nearly a week after the disappearance of four adult friends, authorities said Friday.

It wasn’t clear if the remains were of the four men, Okmulgee Police Chief Joe Prentice told reporters

Authorities were working to document and recover them, he said.

“This process will take some time, and currently, we have more questions than answers,” he said.

The department on Tuesday named the missing men as Mark Chastain, 32; Billy Chastain, 30; Mike Sparks, 32;

Alex Stevens, 29. Relatives had reported them missing earlier, the department said in a statement.
