Police in Indiana found human remains in the backyard of a man recently charged with the murders of two women, Fox41 reports.

The remains were found in William "Clyde" Gibson III's backyard in New Albany, Ind. The 54-year-old is charged with the recent murder of 75-year-old Christine Whitis and the 2002 murder of 45-year-old Karen Hodella.

Floyd County Prosecutor Keith Henderson says the remains found Friday evening in Gibson's backyard are not those of Whitis or Hodella, but rather a third victim.

Authorities plan to identify the remains Saturday. 

Officials say the remains have been in the backyard for a matter of weeks or months.

Henderson says the remains were found in an area close to the home.

Crews plan to continue digging throughout Saturday night.

Henderson says that authorities are going off leads and will follow up on any new information they may get.

Gibson was arrested last week after Whitis' body was discovered inside his home. 

Prosecutor Keith Henderson said on Tuesday that Gibson "implicated himself" in both cases.

Detectives from other jurisdictions are watching the ongoing search as they pursue leads in missing persons cases.

One of the cases involves 35-year-old Stephanie Kirk of Charlestown, who was reported missing after she was last seen March 25 in New Albany.

If convicted of the current charges against him, Gibson could be sentenced to 160 years in prison
