Authorities say DNA evidence led to the arrest of a man in the 20-year-old killings of two young women who vanished on bike rides near Phoenix's canal system.

Police arrested 42-year-old Bryan Patrick Miller late Tuesday in the deaths of 22-year-old Angela Brosso and 17-year-old Melanie Bernas.

Brosso was killed in November 1992, and Bernas died in September 1993. Both disappeared while bicycling near the Arizona Canal. Brosso's decapitated body was found in the area, while Bernas' body was discovered floating in the water.

Forensic evidence connected the killings within years, but investigators couldn't identify a suspect. Police say DNA evidence recently collected by undercover officers linked Miller to the killings.

Officers searched his home overnight. It's not clear whether he has a lawyer.
