A third suspect arrested Monday in connection with a double homicide in Hastings had helped to plan the shootings and had been at the couple's home the night before they were gunned down at their business, according to sources with knowledge of the investigation. Jamie C. Patton, 18, of East Bethel, was arrested Monday afternoon in connection with the slayings of Peter and Patricia Niedere, who were shot to death at their auto glass business Saturday afternoon in downtown Hastings. Hours after the shootings Saturday, the Niederes' son Matthew, 17, and his classmate, Clayton Keister, also 17, of Blaine, were arrested on suspicion of killing the couple. Matthew Niedere and Keister are senior classmates at Concordia Academy, a Lutheran school, in Roseville. Patton was a senior at Mounds View High School this year. He grew up with Keister and attended Calvin Christian School in Blaine with him. http://www.startribune.com/stories/467/5661228.html Long article but worth the read.
