A state trooper transporting marijuana, a pair of cops ripping off drug cash, a constable smuggling across the Mexican border, and a cop with a bad pain pill habit make this week's hall of shame. Let's get to it:
In Brownsville, Texas, a former reserve officer for the Nueces County constable's office was found guilty last Friday  of smuggling cocaine and heroin across the Gateway International Bridge from Mexico. Mercedes Perez, 54, went down after a drug-sniffing dog alerted on his vehicle and Customs officers found five pounds of heroin and 15 pounds of cocaine concealed inside his car. Perez testified at trial that he didn't know the drugs were in his car. He was convicted of conspiracy to distribute heroin and cocaine and possession with the intent to distribute heroin and cocaine. He faces a mandatory minimum 10 years and could get up to life in federal prison.
In Charleston, West Virginia, a former state trooper pleaded guilty Monday  to being involved in a major marijuana grow operation. Kurt Steffen, 30, was hired as a state trooper in May 2007 and shortly afterward joined with others in an indoor grow op that generated untold thousands of dollars before it was busted in January 2010. When it was busted, authorities found thousands of dollars worth of grow equipment and more than 300 plants. In pleading guilty, Steffen also admitted using his state patrol car to transport the weed. He copped to one federal count each of manufacturing and conspiring to distribute more than 100 pot plants. He's looking at a mandatory minimum five-year prison sentence, and up to 40 years.
In Denville, New Jersey, a former Denville police officer was sentenced last Friday  to three years in prison for ripping off oxycodone and heroin from the department's evidence room. Eugene Blood, 38, a nine-year veteran of the department, had pleaded guilty in December to stealing the drugs in 2010 and 2011, when he was the evidence officer. Before sentencing, Blood apologized for the thefts and said he had developed an addiction to painkillers. Blood's thefts compromised numerous narcotics cases, prosecutors said.
