EL DORADO COUNTY --

There's new information that could break the investigation wide open in the case of a missing Benicia family.

"We possibly have a third set of remains that were located at the inside of the cabin at the original fire scene, and are now treating this as an arson, homicide investigation," El Dorado County Sheriff's Sgt. Todd Hammitt said.

Ten days ago, Adam Buchanan, his girlfriend Molly McAff and their 7-year-old son, Gavin, were staying at their Greenwood area cabin in El Dorado County when a fire broke out.

During their investigation, authorities found what they thought were the remains of two people.

"Initially we thought it was a set of two remains, and now we believe that we do in fact have a third set of remains that we've located inside the cabin," Hammitt said.

Three people, so badly burned, investigators say it's been painstakingly difficult to identify them.

While they wait for positive identification, the El Dorado County Sheriff's Office is moving forward with its investigation, classifying it as arson and homicide.

"Any reason to believe that the public's in danger, are you guys looking for a suspect?" FOX40 asked.

"Absolutely not. As far as the general public being in danger and that's what we really want to stress, is that the general public does not need to worry about their safety," Hammitt said.

Last week, detectives searched the Buchanan's Benicia home, seizing computers and documents.

They also searched his construction company's office.

"The possibility of this being a murder-suicide, has that been ruled out?" FOX40 asked.

"We're not ruling anything out at this point and time," Hammitt said.

Neighbors said during the search, Adam's 16-year-old son, who had reportedly not gone with the family to their cabin, was asked to remain in front of the house during the search.

The El Dorado County Sheriff's Office won't comment on a possible suspect or what was found in Buchanan's home and business.
