The murders of four Portland women have now been classified as the work of a serial killer.

Detectives have linked the murders to a man granted early release from his sentence. Jesse Lee Calhoun, 38, was granted early release after he joined a group of inmates fighting devastating wildfires. Calhoun had been sentenced to four years in prison for felonies including burglary, unauthorized possession of a stolen vehicle, and injuring a police officer and a police dog as they attempted to arrest him. Calhoun's clemency has been revoked, and he is back behind bars. 

So far, Calhoun has been named a person of interest, not a suspect in the death of four women whose bodies were found within 100 miles of each other.
