PHOENIX -- Daryl Donovan Cole Jr. stood before a judge Wednesday charged with three counts of sexual assault, kidnapping, and burglary.

Scottsdale police said the quick arrest is due to brand new DNA technology.

"We can turn things around and in this case are able to get a violent predator off the streets," said Sgt. Mark Clark of Scottsdale police.

Officers said Cole forced his way into a woman's apartment early Saturday morning and sexually assaulted her.  

By Sunday night, the forensics lab was able to match evidence at the scene to Cole's DNA that was in a database on a prior arrest for aggravated robbery.

"We were able to get a known profile from the evidence sample by Sunday after less than 24 hours," said DNA specialist Vickie Beamer.

The brand new Global Filer Express Kit did the work in a third of the time. What would have taken 12 to 15 hours of non-stop work only took three to four.

Police arrested Cole on Monday.  This was the first time DNA technicians used the Global Filer Express Kit on a case and Sgt. Mark Clark said it is a great resource for public safety.
