Family: Slain Couple's Safe Held Jewelry

A Florida sheriff has confirmed that the safe taken from the home of a slain Panhandle couple held only adoption papers and other documents, heirloom jewelry and some of the family's prescription medication.

Escambia County Sheriff David Morgan would not say Friday if the killers of Byrd and Melanie Billings expected to find other items in the microwave-sized safe. Morgan said investigators have not yet determined whether the killers even managed to open the safe, which was found buried in a Pensacola-area backyard with bricks piled on top.

The sheriff's news conference came the afternoon after the Billings' funeral. The couple was known for adopting 13 special needs children.

They were shot to death in their nine-bedroom home west of Pensacola last week.

Meanwhile, the children of Bud and Melanie Billings joined hundreds of friends and relatives at a Pensacola church Friday to say goodbye to a couple who devoted their lives to children in need.

The couple, known for adopting 13 special needs children, was shot to death and a safe was taken from their nine-bedroom home west of Pensacola last week. Six men and a teenager are charged with murder, and a woman, Pamela Long Wiggins, is charged with being an accessory after the fact.

"Their lives centered around children, family and each other. They loved deeply and unconditionally," said family member Ed Brock.

As CBS News correspondent Don Teague reports, eight days after the parents of 17 were murdered in a raid of their home authorities in Pensacola say their investigation is almost complete.

They've recovered the suspected murder weapon along with a safe stolen from the house and arrested 8 people. Despite the complexity and planning of the killing, investigators say the motive appears simple.

State Attorney Bill Eddins said the case was mostly wrapped up.

"In our opinion, this was a home invasion robbery where the people stole a safe," he said. "It was as simple as that as to the motive."

Authorities say more arrests could follow. They've brought the Drug Enforcement Agency on the case, but insist the DEA is investigating the suspects, not the victims.
