Colorado authorities say a man wanted in a 32-year-old slaying in Greeley has been arrested in Florida.
Weld County sheriff John Cooke says that 51-year-old Marcello Maldonado-Perez was arrested Tuesday morning at his home in Port Charlotte, Florida. He was being held without bond.
Investigators say DNA taken from him while he served time in Texas links him to the sexual assault and stabbing of 22-year-old Mary Pierce in 1977. Pierce was kidnapped from the 7-11 store where she worked. Her body was found two days later.
Evidence from the case was submitted to state investigators for DNA testing in 2003 and 2006. Authorities say they learned last year that DNA from the case matched a sample taken from Maldonado-Perez before he was released from prison in 2008.
