MILWAUKEE, Wis. (WTAQ) - A man was sentenced to 2 years in prison Thursday, for buying the gun that another man allegedly used to shoot 2 Milwaukee police officers. 22-year-old Jacob Collins got a longer than sentence than most defendants get for so-called “straw buying.” But Federal Judge Lynn Adelman ordered a term that was far short of the 10 years suggested by prosecutors. They wanted to send a message against “straw buying” – in which a person with no criminal record buys weapons for felons who are not allowed to have them. Assistant U.S. Attorney John Manning said Collins knew the gun would probably be used in a crime. Defense lawyer Daniel Stiller asked for probation. He said Collins only has the intelligence of a 3rd grader, and he didn’t realize they’d be used in a shooting incident. 19-year-old Julius Burton is charged with using the gun to shoot officers Graham Kunisch and Bryan Norberg in broad daylight last summer. Burton’s criminal case is still pending. He has pleaded not guilty to attempted homicide.
