> The video above is prior coverage about the case.
Peter Arguello was shot and killed at his business in the 7200-block of W. 38th Ave. on Nov. 29.
In early March, Wheat Ridge police issued a warrant for Michael McCormack. He was located in Black Hawk and taken into custody on Wednesday on charges of second-degree murder, second-degree kidnapping, aggravated robbery and motor vehicle theft.
The other suspect, Charles Shay, was initially arrested in connection with a burglary at the victim’s store that occurred about a month after Arguello was killed. After Shay was arrested for the burglary, he told investigators he had broken into the jewelry store on Dec. 26 because he heard about the homicide and saw it as a crime of opportunity.
Shay is being held on charges including murder, kidnapping, robbery, motor vehicle theft, arson, burglary and tampering with evidence. His next court appearance is set for May 14.
