CONWAY, Ark. (AP) - Authorities in Faulkner County say a preliminary report from the medical examiner shows that a slain roller rink owner died from one gunshot wound to the head.

The Log Cabin Democrat reports (http://is.gd/DbMwk5 ) that authorities wouldn't say what type of gun was used in the death of 60-year-old Larry W. Billings. Police say Billings' teenage son found his father's body Monday night.

Police say Billings was dead for several hours before he was discovered.

Billings was the longtime owner of Conway Roller Rink.

Investigators are still looking for Billings' blue 2007 Nissan Titan truck, which was discovered missing from Billings' home. The truck has an Arkansas license plate of 631 MEM.

Authorities say there were no signs of struggle or forced entry to the home.
