Authorities say that preliminary reports from the medical examiner indicate local business owner Larry W. Billings, 60, died of a single gunshot wound to the head.
Officials declined to comment on the caliber or type of firearm but said it appeared Billings was dead for several hours before he was discovered.
Billings was the longtime owner of Conway Roller Rink. He was found on Monday evening in his bed by a teenage son, who alerted neighbors before calling police.
Investigators are still looking for a blue 2007 Nissan Titan pickup, license plate number 631 MEM, that belonged to Billings. The vehicle was entered into ACIC as stolen after it was discovered missing from the residence.
There were no signs of struggle or forced entry to the home and authorities have named no suspect in the case.
"We are looking at every potential thing that comes across us," said FCSO Capt. Matt Rice on Wednesday.
Billings had recently entered into a business agreement to sell his Oak Street real estate for development.
Anyone with information on the missing Nissan Titan is asked to contact the Faulkner County Sheriff's Office at (501) 450-4914.
