WESTMINSTER, Colo. — A 7-year-old boy playing with an unsecured shotgun accidentally shot and killed his 3-year-old sister inside a home Tuesday morning, according to a release from the Westminster Police Department.
The mother of the victim, 24-year-old Michaela Dawn Harman, was arrested on suspicion of child abuse resulting in death.
