WAILUKU  >> The discovery of a missing pregnant Maui woman’s jawbone helped authorities file a murder charge against her ex-boyfriend, a person familiar with the investigation told the Associated Press. 

The person, who is not authorized to speak publicly, told the AP Wednesday that the discovery of Carly Scott’s jawbone was a key turning point in the case.

The person said when maggot-infested clothes belonging to Scott were found, it became clear she was dead. 

The person declined to reveal exactly how authorities linked the jawbone to Steven Capobianco, Scott’s former boyfriend and father of her child.

Authorities identified Scott through dental records. 

Capobianco has pleaded not guilty to charges of murder and arson. He’s accused of killing Scott in February and burning her sport utility vehicle in an attempt to cover up the crime.
