This Week's Corrupt Cops Stories

Perverted probation officers, greedy jail guards, and a perjury plot backfires. Let's get to it:

In Portland, Oregon, a former US probation officer pleaded guilty April 28 to coercing sexual favors from female defendants, including drug offenders, under his supervision. Mark John Walker, 52, admitted to violating the victims' constitutional rights to bodily integrity while acting under color of law. In one case, Walker forced the victim to have sex with him against her will when he visited her home as part of his official duties. In other cases, he kissed victims or touched their breasts, buttocks, and inner thighs without their consent. Under the plea agreement, both sides have agreed to recommend a 10-year prison sentence when he is sentenced June 18.

In Cambridge, Massachusetts, a Middlesex County Sheriff's Department sergeant was arrested Monday on drug charges after allegedly receiving cocaine from an undercover state trooper. Sgt. Michael Dell'Isola, 51, is charged with trafficking cocaine. He went down after the sheriff's office received an anonymous tip last month and ended up setting up a sting. Dell'Isola, who worked at the Cambridge Jail, took cocaine and $500 cash from the undercover trooper, and was arrested on the spot. The 28-year veteran was being held pending a bail hearing.

In Detroit, a former Inskster police officer was sentenced Tuesday for his role in a perjury scheme in a 2005 cocaine trafficking trial. Robert McArthur was sentenced to 90 days in jail for misdemeanor willful neglect of duty. He could have faced up to life in prison on felony perjury charges, but accepted a plea bargain that includes his testifying next month against one of his co-defendants, retired Wayne County Judge Mary Waterstone. McArthur, Waterstone, another Inkster police officer, and Wayne County's former top drug prosecutor were all charged with perjury for letting a paid police informant testify without revealing that he was a key participant in the operation. Former prosecutor Karen Plants and former Inskter Police Sgt. Scott Rechtzigel have also take plea deals in the case and received short jail sentences. Waterstone has turned down all plea offers and faces trail June 7.
