Alaina Babette Caudill, 26, was shot in the head and killed outside her Kenosha, Wisconsin home on May 1, 2010. She had been attending Gateway College and worked at places including The Shanty in Wadsworth, Illinois. Friends described her as having a vibrant personality and a beautiful smile.

The shooter was identified as her ex-boyfriend, Christopher Stuart. Alaina had broken off the relationship in January 2010 amid what friends called increasingly controlling behavior. She filed a police report against Stuart reporting threats just 36 hours before she was killed; the attack happened while he was reportedly lying in wait outside her home. The killing has been described as a result of domestic violence.
