Police in Daytona Beach, Florida, have arrested a person of interest tied to the murders of four friends in Okmulgee, Oklahoma, last week.

The four men, including Mark Chastain, 32; Billy Chastain, 30; Mike Sparks, 32; and Alex Stevens, 29, went missing on Oct. 9 after leaving for a bike ride from Billy Chastain's house.

Daytona Beach police on Tuesday arrested Joe Kennedy, 67 — who was named as a person of interest in the four murders on Monday — on charges of motor vehicle theft. He is being held without bond at the Volusia County Jail.

Authorities in Okmulgee County also issued a warrant for Kennedy's arrest in connection to a shooting incident he was sentenced for in 2012.

A witness told police that he was invited to join the four men that night to "hit a lick big enough for all of them," or commit a criminal act, Okmulgee Police Chief Joe Prentice said at a press conference on Monday. 

It is unclear what type of crime they allegedly planned to commit.
