Second Safe In Billings Home Contained $100,000

PENSACOLA, Florida (CNN) -- A safe found in the home of a slain Florida couple known for adopting special-needs children contained about $100,000, a source familiar with the investigation told CNN late Tuesday.

Byrd and Melanie Billings, known for adopting special-needs children, were laid to rest Friday.

The safe is the second one belonging to Byrd and Melanie Billings of Beulah, Florida. The source said the suspects in the Billingses' shooting deaths believed the safe was the mother lode of valuables at the house, but were unable to get into it.

Escambia County Sheriff David Morgan would not confirm existence of a second safe and said he was "not at liberty to address that issue."

"I can only confirm the items we know were removed from the Billings home," Morgan said -- a small safe that contained prescription medication, family documents and some jewelry, and a briefcase that contained nothing significant.

Billings family attorney Crystal Spencer told CNN she had no comment because of the ongoing investigation.

Police have said a safe containing prescription medication, family documents and some jewelry was taken from the Billings home at the time of the slayings. It was found in a suspect's backyard, buried with bricks on top in what Morgan said was an "obvious attempt to conceal it."

The Billingses had adopted 13 children, and each had two biological children. Police have said nine of the children were home at the time of the home invasion; one of them managed to flee and seek help from a neighbor.

Melanie Billings' daughter, Ashley Markham, said she is in the process of moving into the couple's home to take care of the children. "That decision was a request of my mother's. ... And we're going to honor her wishes and just do everything that she would have done," she said.
