Kathy Kinsley points to this summary of how Luke Helder was caught, compiled by Mary Wehmeier.
Yesterday about 5 PM Pacific Time, Luke J. Helder, AKA Mailbomb Boy was arrested after he tried to outrun the Nevada Highway Patrol for over 50 miles on I-80. The car chase exceeded over 100 mph at times . Federal authorities were tipped off by his father after a letter he received according to court documents filed Wednesday. Obviously Dad wasn't thrilled at the letter he got from Luke.The hand-written letter, Helder told investigators, referred to death and dying and contained several anti-government comments. After receiving the letter at his home in Pine Island, Minn., Cameron Helder talked by phone with his son's roommate in Menomonie. The roommate, James Divine, and two friends searched Luke Helder's bedroom and found clues under the bed that suggested Helder might be involved in the bombings. They found a bag with nails, paper clips, a funnel and two plastic bottles labeled shotgun or gun powder, according to the court papers.
