Coffee cup DNA solves decades-old golf course sexual assaults cold case.

A Michigan man, identified using genetic genealogy technology, has been arrested in connection with two decades-old sexual assault cases that occurred on golf courses in different states. Kurt Alan Rillema, an "avid golfer," was identified through DNA evidence from the sexual assault of a 22-year-old woman at a Michigan golf course in 1999, which matched DNA evidence from a violent rape in Pennsylvania, also on a golf course, at the Penn State University campus in 2000. DNA from a coffee cup ultimately led to Rillema's arrest. He faces charges in both states and could face up to life in prison if convicted.
