Suspect arrested in killing of 3 women in Utah

A suspect in the killing of three women in the US state of Utah has been taken into custody in neighbouring Colorado.

Authorities received a call that two women's bodies had been discovered on a hiking trail in Wayne County on Wednesday. Investigators then found a third woman dead at a residence nearby, according to the Utah Department of Public Safety.

They tracked a possible killer, who was driving one of the victims' cars, through the south-eastern part of the state, a remote region with many public lands, the department said.

One woman was in her 30s, another in her 60s, and the third woman was in her 80s, the department said. The victims have not been publicly identified.

The suspect in the triple homicide drove through Arizona into Colorado, where he was arrested "without incident" by Colorado law enforcement on Thursday morning, the Utah public safety department said.

Investigators do not believe the suspect, a 22-year-old man from Iowa, has any connection to the victims, according to 2KUTV, an affiliate of BBC's US partner, CBS News.

Wayne County has a relatively small population of about 2,500 and many of its schools and businesses closed during Wednesday's manhunt.
