Police labeled Slater the prime suspect even though the store's security system videocassette recorder was stolen. The security system theft is interesting in that a store's security system is what led to Slater's arrest for two armed robberies in Arkansas in 1989. He served nine years in prison for those robberies before being released in 1998. The man Porter County police describe as the prime suspect in Kathryn Pokorny's murder sits in the Lake County Jail on a parole violation. Porter County police expect to continue interviewing him about the night of Aug. 10 when Pokorny, the clerk working at the Marathon station at U.S. 6 and Meridian in Liberty Township, was robbed and murdered.
Slater is the doughnut delivery driver who serviced the station that night.
Pokorny signed for the doughnuts at 11 p.m., police said. Anyone with information about the case should call the Porter County Sheriff's Department at 465-1515.
