The most recent shooting happened on westbound 80/94, but the victim told police her first interaction with the shooter’s car took place down on 25th Avenue because of potholes. It occurred around 9 p.m.

A 33-year-old Lansing woman told police she was driving slowly because of potholes. When she noticed the car behind her following too closely, she hit her brakes to get the driver to back off.

Instead, the driver pulled in front of her as they turned onto Burr Street. Moments later, as they entered the interstate, the man pulled up alongside her in a red four-door car with dark-tinted windows.

Wednesday a man was shot on I-80/94 near Cline Avenue.
