Larry Billings, 60, was found dead in his home in Conway late last month with a single gunshot wound to the head.
Billings dark blue NissanTitan truck with license plate number 631 MEM was also taken from the scene and is still not recovered.
"We're just baffled," said Billings' daughter Alicia Page. "Because I don't know anybody who didn't like my dad, with all the posts it seems everyone genuinely seemed to love him and we're just floored."
