It's called rapid DNA.
HPD launched a pilot program with the company ANDE to test a machine that runs DNA tests in under two hours.
"This rapid DNA is the future. It comes down to when mathematicians stopped using abacuses and started using calculators. It's that important to criminal justice," said Lt. Warren Meeler, Houston Police Department, Homicide Division.
The machine has a variety of applications, including testing evidence at crime scenes.
For example, detectives could run a rapid DNA test if they find a weapon at a murder scene. They would swap the weapon and swab anyone who might be involved. Then machine would compare the samples to potentially reveal whose DNA is on the weapon.
