"Four people have been arrested and others may still be on the loose after a shootout Wednesday morning on I-43 that injured a man and prompted authorities to shut down the southbound lanes for two-and-a-half hours.
"Southbound I-43 from W. Fond du Lac Ave. to W. Becher St. was closed while investigators walked down the highway to recover shell casings and bullet fragments, the Milwaukee County Sheriff's Office said. The highway lanes reopened about 2:30 p.m. Wednesday.
"The sprawling crime investigation began Wednesday morning when deputies responded to reports of a shooting on the freeway in the Marquette Interchange near Highland Ave. about 10:10 a.m., according to the Sheriff's Office.
"Investigators determined that more than a dozen shots were fired into a vehicle during a gunfire exchange with another vehicle. A person in one vehicle was grazed by a bullet."
