Rats infested the Houston Police Department's evidence room and broke into a package of mushrooms, possibly disrupting open drug-related cases.

To illustrate the problem, Houston police Chief J. Noe Diaz pointed to one piece of cocaine evidence from 1996 that was still in the lockup. The individual tied to the drugs pleaded guilty, was sentenced to 20 years in prison and has since been released, he said.

The rodents are enjoying marijuana at the Houston Police Department that has been sitting in evidence for years.

HPD and the Harris County District Attorney's office is changing how evidence is stored after a 'drug-addicted rat' problem caused them to revaluate there evidence property room.
