David Martin, research associate with Wayne State University's Center for Urban Studies, comments in parts one and two of a Detroit Free Press series on the Michigan Department of Corrections (MDOC) and its supervision of parolees and probationers. The Free Press investigation concluded that convicts who should have been behind bars or closely monitored were left on the streets unchecked. A total of 88 parolees and probationers were suspected, arrested or convicted in 95 murders between Jan. 1, 2010, and Aug. 31. The number nearly doubled from 2010 to 2011 -- from 21 to 38. In the first eight months of this year, 36 killings have been attributed to ex-cons under MDOC supervision, according to department critical incident reports. Martin has been critical of the way offenders are supervised. He said too much of it is done by phone, and officials have told him some agents don't go into Detroit neighborhoods because it is dangerous. "I don't see enough field supervision going on in the city of Detroit," Martin said.
