The Marion County Sheriff’s office arrested one man Friday in connection with a double slaying last month at a rural farmhouse. The bodies of John Caswell and Steve Emerson were found on October 24 at a rural home south of Knoxville. Marion County Sheriff Marvin Van Haaften says after questioning many people who said they’d been at the place that day, authorities built a strong case to get an arrest warrant. They arrested Howard Paul Garrison of Knoxville and he’s charged with two counts of first-degree murder. Garrison’s bond is set at one-million dollars, and sheriff Van Haaften says investigators and the crime lab put in a lot of work questioning people and comparing bullets that killed the two men with the gun Garrison owned. He got a lawyer within hours of the discovery of the bodies, and that attorney still hasn’t let authorities question Garrison himself. The sheriff now is asking people “on the street” to call with more information, if they’d been holding off till they were certain Garrison was behind bars.
