ST. PAUL — A former South Dakota National Guardsman who killed a 33-year-old bicyclist on a road in southwestern Minnesota last summer warned others Monday of the dangers of distracted driving.

Christopher Weber, 27, pleaded guilty to criminal vehicular homicide for the crash that killed Andrea Boeve of Steen on June 30, 2014. Weber just finished a six-month jail sentence and will serve three more months next year and three more in 2017.

Weber came to St. Paul Monday as part of the Minnesota State Patrol’s expanding campaign against distracted driving, which has focused on texting and using mobile devices, Minnesota Public Radio News reported.
