Twenty-nine-year old Australian twin sisters in the U.S. on cultural exchange visas may have made a bizarre suicide pact.
Authorities discovered the two women at a shooting range outside of Denver, Colorado with gunshot wounds to the head. One sister was killed and the other was moved from critical to serious condition in a nearby hospital. The sister that survived is considered to be in too grave of a state to be questioned.
Authorities are still trying to discover if what happened was a double suicide, murder-suicide or just a tragic accident.
