A child predator was on the loose Friday after police said he cut off his electric monitor.
Marvin Munson was convicted of breaking into a house and forcing a 9-year-old girl to perform a sex act on him in 1986.
When he got out of prison, police said he broke into another home and forced an 8-year-old girl to perform a sex act at knifepoint.
Munson went to prison again, but he was released last month.
Investigators said they were using the electronic monitor to track him before he cut it off.
They believe Munson might be in the Houston or Beaumont areas.
If you have any information on his whereabouts, call Crime Stoppers at 713-222-TIPS.
