DNA Evidence Nails Two

Houston police arrest and charge two suspects in separate sexual assault cases. The two were successfully linked to the cases through testing of DNA evidence by the HPD Crime Lab. Pat Hernandez has the story.

DNA technology to help solve cases is becoming common place as it makes the job of investigators even more effective. 24 yr old Marlon Jovel Hernandez, a Honduran national, confessed to a pair of assaults that occurred late last year.  He's accused of breaking into the victims' apartments and sexually assaulting them. This is HPD Special Crimes Investigator Jimmy DeLosSantos:

suspects"The guy didn't admit to anything at first, but we got to the point where we got out there and we swabbed a whole lot of people, and luckily for us, we were able to get a DNA match on him and stop him before he did anything else."

The other case involves 30 year old Mariano Jimmy Soto, who is accused of brutally assaulting his female victim last summer. Investigator Robert Wieners says this case was easier to crack because Soto had a rap sheet.

"In fact, when we picked him up after this warrant was filed, he was appearing in court for felony possession of a firearm."

HPD Lab Director Irma Rios says DNA technology has improved in a very short period of time.

"That is one powerful tool for law enforcement obviously, along with very good investigative work. So, if somebody's been victimized, collect that DNA evidence so that we can identify these perpetrators."

Rios says the national DNA data base contains some 9-million convicted offenders.
