The owners of the RV that had been rented out to a group of bachelor party revelers who found a body inside a storage compartment "are not considered suspects," Anoka County investigators told the Star Tribune.
The body of Kevin Casserly, 22, of Anoka, was found May 1 after the bachelor party group on its way to the Kentucky Derby smelled an odor and stopped to investigate along Highway 61 in Winona.
Casserly's family had reported him missing in November. Officials have not yet disclosed the cause of death.
The owners of the vehicle were “immediately known to us, have cooperated with us fully and are not considered suspects in anything,” Anoka County Sheriff’s Cmdr. Paul Sommer told the Star Tribune.
Police and members of the bachelor party have not disclosed the identity of the RV owners, the newspaper notes.
The investigation continues, authorities say. Many questions in the mysterious case remain unanswered: How did Casserly's body end up in the RV? Why did he disappear last fall?
Several weeks after he disappeared in November, his family had feared the worst.
