Delavan police are calling the Monday shooting in Darien a domestic violence incident because two of the people involved had a previous relationship. Casey J. DePriest and Jenna M. Brovold broke up two months ago. Investigators say DePriest shot Brovold to death, wounded her 26-year-old brother, Evan, then turned his gun on himself. Jenna Brovold had told her sister earlier in the day she was afraid to stay in her home because DePriest had threatened her. DePriest and his victim had dated for about a year-and-a-half before ending the relationship.
