The Boone County Sheriff's Department has identified two shooting victims and a man who was shot to death by a sheriff's deputy during the weekend.

The department says in a news release that 53-year-old Deborah Koontz and her 51-year-old brother, Donald Wilson, were shot to death Saturday night near Columbia. A third man, 44-year-old Willie Mays, was hospitalized with a gunshot wound.

The suspect in the shootings, 28-year-old Cornelius Parker, was pursued by Boone County deputies. Boone County authorities Parker died after he got out of his vehicle and exchanged gunfire with a deputy.

Parker lived with the three victims but investigators are still trying to determine a motive for the shooting.

The 32-year-old deputy involved in shooting has over 11 years in law enforcement.
