Three shootings have been reported along a busy interstate in Milwaukee in a two-week stretch.

It was not immediately known whether the incidents were connected.

The latest shooting happened Sunday evening and closed the southbound lanes of Interstate 43 as deputies with the Milwaukee County Sheriff’s Office canvassed the roadway for evidence, according to reports. No injuries were reported.

On Oct. 16, the northbound lanes of I-43 were shut down after an individual said his vehicle was shot at when he gestured to the occupants of a Ford Taurus for cutting him off.
