Orland Park Police Investigation Near Orland Grove Preserve Closes 143rd Street

Orland Park police shut down a stretch of West 143rd Street on Saturday afternoon as officers assisted Cook County Forest Preserve Police with an investigation at the southern edge of the Orland Grove nature preserve, authorities said.

The closure, announced around 3:20 p.m., affected 143rd Street in both directions between West Avenue and Highland Avenue. In a social media post, Orland Park police advised the public to steer clear of the area while the investigation was underway.

"The roadway is shut down in both directions east and west at West Avenue and at Highland Avenue on 143rd. Please avoid the area," the department said.

Details about the nature of the investigation were not immediately released, and it was not clear how long the road would remain closed. The Orland Grove preserve, a wooded natural area managed by the Forest Preserves of Cook County, sits along the southern portion of the closure zone.

Drivers in the southwest suburb were advised to plan alternate routes around the affected corridor while officers remained on scene. The involvement of both municipal and county forest preserve police reflects the preserve's location within Orland Park's boundaries and the overlapping jurisdiction that applies to investigations on forest preserve land.

This is a developing story. Anyone with information that could assist investigators is encouraged to contact Orland Park police or Cook County Forest Preserve Police.
