Governor Eric Holcomb released the following statement Sunday on the death of Captain Matthew Tomkiewicz of Fort Wayne:

“Janet and I send our sincere condolences to Captain Matthew Tomkiewicz's family and friends, especially in the tough days ahead. We ask all Hoosiers to surround the family with love and never-ending appreciation for all Captain Tomkiewicz gave to our state and nation.”
