PHOENIX -- Phoenix police and the Maricopa County Attorney's Office credit a relatively new partnership for solving more cold case crimes.
They announced their latest arrest in a 25-year-old case at police headquarters Wednesday and expect more to come.
"There's definitely a few that are close to being ready, we think," Det. JJ Alberta told 3TV.
Crime lab technology and the National DNA Database are key, but detectives also point to simpler things that are helping them crack cold cases.
They created a standard template for each case, with the basic information and evidence. It makes it easier for anyone involved, now or down the road, to understand the main players and evidence in each case.
Plus, the Maricopa County Attorney's Office added three experienced homicide detectives to the staff. They were hired specifically to review and analyze evidence in unsolved murder cases.
"I think for families of some of those cases, it does mean renewed hope. It does mean renewed confidence that we're not letting these matters just disappear," county attorney's office spokesman Jerry Cobb told 3TV.
In Phoenix, 2,500 cold cases remain unsolved.
"I think you'll be hearing more and more cases come to a conclusion," Cobb said.
"It does allows us to review and follow up on leads with more cases than we would without the extra bodies helping us out," Alberta added.
