LAS CRUCES, N.M. (KRQE) - This week will mark the 21st anniversary of the Bowling Alley Murders in Las Cruces, New Mexico.
Despite intense efforts by authorities, the murderers' identities remain a mystery.
Back in 1990, two men robbed the alley at gunpoint, shooting seven and killing four.
Frustrated investigators are still chasing leads and still working to keep the case in the headlines in hopes that someone will come forward with a tip.
