A man in Nevada prison for attempted murder is suspected of killing four people in Colorado in 1984, according to state authorities.

NBC affiliate KUSA reported earlier this week that Alex Christopher Ewing became a suspect in several cold case homicides.

Ewing, 57, has been serving a sentence of up to 40 years at the Northern Nevada Correctional Center for charges including attempted murder and burglary for an attack in Henderson.

Colorado authorities said at a press conference Friday that a DNA sample from Ewing matched the DNA profile of the person responsible for killing Bruce, Debra and Melissa Bennett and Patricia Louise Smith.

The Bennetts were killed in their Aurora home in January 1984. Vanessa Bennett, the youngest daughter of the family, was badly beaten but survived.

Smith was also killed in her home in Lakewood, Colo., that same month. Authorities eventually matched DNA from Smith's murder to the Bennetts' case, according to KUSA.

In a statement, Nevada Attorney General Adam Laxalt said a DNA sample was collected from Ewing in accordance with state law and sent to the Combined DNA Index System.

The Colorado Bureau of Investigations learned in July that it was a direct match to both cases, according to the attorney general's office, and a search warrant was issued to collect a cheek swab from Ewing.

Ewing was convicted for attempted murder, burglary and other charges after he escaped a Mohave County transport while in Henderson in August 1984. Authorities said he entered a home and attacked a couple with a wooden pick axe handle.
