A housekeeper discovered Faull's body in a hallway of his home with a gunshot wound to the back of his head.
Authorities investigating the homicide are speaking to another person as they pursue multiple leads.
A laptop computer and cell phone are missing from Faull's home.
Police do not have a motive in the deadly shooting.
