LUBBOCK, Texas -

On Tuesday, Lubbock Police confirmed a man killed his wife nearly 12 years ago. It was DNA that finally broke the case of Selena Kuykendall's death. 

This technology had been around since March of 2016. DNA technical leader Naomi McDonald said the priority has been to use the new technology for current cases. Then, move on to unsolved crimes like the death of Selena Kuykendall. 

"It's more sensitive and it allows us to look at more locations, more DNA locations then we could before," McDonald said. 

Back in 2007, a detective with LPD collected a piece of evidence that then, was not considered useful. Now, it is what allowed investigators to name Selena's killer. 

"It is important to collect things as early as possible," McDonald said. "Once they're in a stable environment, DNA evidence can last a really long time." 

Both McDonald and other investigators said they are working on other unsolved cases. The police chief states on Tuesday he is confident they have a break in at least one case. 

"We hope to go back to some of these older cases and possibly give some investigative leads to the agencies," McDonald said.

The lab here in Lubbock covers 76 counties and staff 15 scientists. McDonald urges the public to be patient as they are working to help each agency in that vast area.
