On Feb. 10, 1990, two men shot seven people while robbing a bowling alley in Las Cruces, New Mexico. Four of the victims died. Three of the dead were children, ages 13, 6 and 2. All of the victims were shot at point-blank range. Thirty years have passed and the killers have yet to be brought to justice in what is now one of the bloodiest mass shootings in the nation.
