INDIANAPOLIS – A central Indiana police chief is still hoping for a break in the unsolved killings of six people two decades after that multistate crime spree.

Cumberland Police Chief Michael Crooke was an Indianapolis homicide detective when 26-year-old Robin Fuldauer became the first victim in April 1992. She was slain at an Indianapolis shoe store.

Crooke retired from the Indianapolis police in 2004, but he told The Indianapolis Star (http://indy.st/ZkVvhl) he continues working on the case and hears from someone about once a month about the killings.

Four of the six killings were in strip malls along Interstate 70, two in Missouri and two in Indiana. Two other victims were slain at a Wichita, Kan., bridal shop near Interstate 35.

All six victims were killed by the same .22-caliber weapon.
