Good cop, bad cop?

OK, so if you're a former cop yourself, you'd think you would be slick enough to avoid being arrested for a crime spree, right? Well, maybe not: Police have made an arrest in a string of Montgomery County bank robberies, and the prime suspect is a former HPD officer. His name is Raymond Martinez, and he's been charged with the aggravated robbery of a Wachovia branch in April; Sgt. Bryan Carlisle of the Shenandoah Police Department told KTRK he's also a suspect in at least three other bank robberies in the area.

Police say the robber dressed as a security guard during most of the robberies. During one, at a Capitol One branch in August, he left out the security guard's outfit but did don a fanny pack — and police still thought he had some kind of background in law enforcement "simply based upon the way the suspect was dresses and in the manner in which he carried himself," Carlisle said. We guess he was wearing that fanny pack with a whole lot of authority.

HPD says Martinez was on the force from March 1999 until May 2004, when he was fired after pleading guilty to official oppression. His dad told Channel 13 that Martinez hasn't held a job since then, but said he isn't a bank robber. Martinez's wife also said he's innocent and pledged to prove it. As for the police, they said they have to make arrests even when suspects were once cops: "We don't enjoy being put in that situation, but we have no qualms in enforcing the law and taking that suspect into custody," Carlisle said.
