Police from Fitchburg and Madison and deputies from the Dane County Sheriff’s Office on Wednesday morning were also in the 2500 block of Post Road, where one of the vehicles seen leaving the shooting scene was pulled over and one or more occupants were arrested. DeSpain said it wasn’t clear how or whether those arrested were in any way involved in the shooting or knew anything about it.

Students at Leopold Elementary School — directly across Post Road from where the vehicle was pulled over — were ordered inside as police and school authorities put the school in lockdown as a precaution.

Koval said the shooter on McDivitt Road was believed to have left the scene in a vehicle. It wasn’t clear if the bullets were fired from one or more vehicles or if the shooter or shooters were also in the street at the time.

After the shooting, longtime resident Lynn Siewert said shooting incidents were getting worse in the neighborhood — “This summer has been the worst of them all,” she said — though Wednesday’s incident was the first time she knew of anyone getting hit and one of the rare times bullets have flown during daylight hours.

Siewert said she has most often heard shots fired in the neighborhood around 9 p.m., and sometimes around 2 a.m., calling the police to report every incident.
