A group of United States Marshalls from Milwaukee, Wisconsin are in the Dubuque area today (Friday), helping one of their own search for his missing son. Twenty-four-year-old Matthew Kruziki was passing through Dubuque when he disappeared early last Saturday morning. Matthew’s father, Bill Kruziki, is a U.S. Marshall and he says he’s pleased with how local officials have handled the search. “I think the Chief (of Police) in East Dubuque has done an excellent job,” Kruziki says. “He’s taken on this thing personally and he’s put all of his time and effort into it and I can’t ask for anything more.” The Illinois State Police flew over the Dubuque area yesterday, but found no trace of Kruziki’s son who was last seen outside a bar in East Dubuque, Illinois. Kruziki says his co-workers — fellow U.S. Marshalls — will scour the area today, helping in the search. “I want to make sure in my own heart that we did everything we can and if I have those resources available to me, I’m going to use them,” Kruziki says. He has set Sunday as a personal deadline. If Kruziki hasn’t found his son by the end of the weekend, he’ll head back home to Wisconsin. “You always need closure,” he says. “I don’t want to leave this weekend without finding my son, so our goal this weekend is to do everything we possibly can.” East Dubuque Police say the next step they’ll take in the investigation is to search the Mississippi River.
