On the evening of June 30, 1975, 25-year-old Kathleen Tennant was shot and killed outside her home in Pueblo, Colorado. Witnesses reported a greenish-blue late 1960s Mustang pulled into her driveway; as Kathleen approached the car she was fatally shot and the occupants fled. The Pueblo Police Department opened a homicide investigation and took witness statements describing the vehicle, but no significant leads developed in the days and weeks after the killing.

Decades later the case remains unsolved. No arrests have been announced and no suspects have been publicly identified. The identities of the person or persons who were inside that Mustang and the motive for the attack are still unknown.

If anyone remembers seeing a late 1960s greenish-blue Mustang in the neighborhood on June 30, 1975, or has information about Kathleen’s death, please come forward.
