Last night, Shawnee police had a checkpoint to hand out flyers in the Gerry Grovenburg murder. The 61-year-old Grovenburg, who was married with a grown son, was found dead behind the counter of his liquor store in May, and police are still looking for the person who killed him.
About 240 vehicles passed through the checkpoint last night, Capt. Rob Moser said. Investigators wanted to reach people who regularly drive through that neighborhood, in case they saw something the night of Grovenburg's slaying. They also happened to catch one drunk driver during the checkpoint. Shawnee police checked with the district attorney's office before scheduling the checkpoint, Moser said.
Here's a list of guidelines that, generally, police must meet when setting up a checkpoint, if you were curious. Checkpoints are used most commonly for DUI cases, though they've been operated for other reasons, like checking for drivers licenses. (Something that KCPD has been doing a lot lately.) I found a few cities that have done checkpoints like the one Shawnee had last night, though they're fairly rare.
Anyone with information about Grovenburg's homicide is asked to call the TIPS Hotline at 816-474-TIPS (474-8477) or the Shawnee police at 913-262-2150.
