Dubuque Police say a man threw a pocketknife through a vehicle window, shattering the glass and injuring a toddler Tuesday in Dubuque. 29 year old Joshua Krogman was arrested Tuesday on charges of child endangerment with injury, child endangerment and fourth-degree criminal mischief. Reports say Krogman was arguing with his ex-girlfriend, 26 year old Kayla Blackman of Dubuque, while she drove Krogman and two children on West Third Street. Blackman stopped and made Krogman exit the vehicle. As he did so, he threw a pocketknife through a vehicle window. The glass shattered and caused a laceration on the forehead of a 2-year-old girl. She was treated for her injuries at UnityPoint Health-Finley Hospital. Krogman admitted to throwing the knife into the window.
