A Beloit man will serve 3.5 years in prison for dealing drugs on 12 occasions over the last year, according to the state Department of Justice.

A United States attorney for the Western District of Wisconsin said in a statement Thursday that Kelvin Haley, 30, was sentenced Wednesday to 42 months imprisonment and six years of supervised release for distribution of heroin from August and September of 2012.

On Jan. 29, 2013, Haley pleaded guilty to a single count of heroin delivery that occurred on Aug. 27, 2012.

Haley was sentenced based on his delivery of heroin on nine occasions over a two-month period and evidence that he delivered crack cocaine on three occasions in the spring of 2012 while he was on probation for other offenses.

DOJ said the charge against Haley was the result of an investigation conducted by the FBI Safe Streets Task Force, which includes the Beloit Police Department, Rock County Sheriff’s Office and the Federal Bureau of Investigation.
