But there may be multiple motives and more arrests are possible after three men were jailed Sunday, two of them on murder charges in the shooting deaths of Byrd and Melanie Billings at their sprawling home near Pensacola, Escambia County Sheriff David Morgan said.

"It began as what we thought was a home invasion. At this point because of the complexity and the ties this family had through the business community, we're moving many other directions. Could be money, could be a whole host of things," Morgan said on the NBC "Today" show.

Morgan also cited the family's business ties in an interview on the CBS "Early Show" but declined to be more specific and said investigators are working on "multiple motives."

Three men have been arrested in connection with the slaying and were expected to have court appearances as early as Monday. Court officials Monday morning could not immediately confirm dates or times.
