Documents say the driver involved in a crash that killed four Dubuque County boys last month failed sobriety tests. According to The Telegraph Herald, a search warrant to take photographs and a blood sample from 24-year old Joseph Connolly of Holy Cross shows deputies smelled alcohol on him following the August 2nd crash at the intersection of two roads near Epworth. Police say Connolly, who was driving a pickup, failed to stop at a stop sign and struck a four-wheeled John Deere gator carrying Sean Kenneally, Mitchell Kluesner, Nicholas Kramer and Bryce Wilwert. All were 14. Three died at the scene of the accident, while the fourth boy died shortly after arriving at a local hospital. Dubuque County Sheriff’s Deputy Tony Dalsing wrote in the warrant that Connolly failed two of three standardized field sobriety tests. No charges have been filed in the case. Online court records indicate Connolly pleaded guilty in 2010 to Operating While Intoxicated, a serious misdemeanor, and in 2013 to Consumption or Intoxication in Public Places, a simple misdemeanor.
