The Milwaukee County Sheriff's Office says that a man has died after a rollover crash where the vehicle crossed the opposite lanes of traffic and went 30 feet off the road into an embankment.
Jose Ortiz-Hernandez, 28, died in the crash. It happened at about 1:50 a.m. New Year's Day on I-43 south of Silver Spring Drive.
He was going northbound on the freeway when the car struck the median, then overturned through and beyond the southbound lanes.
A Greenfield Police officer who was off-duty attempted to save Ortiz-Hernandez's life when deputies, police and paramedics attempted to help. He was pronounced dead about a half hour after the crash.
Ortiz-Hernandez was the only person in the vehicle. The Sheriff's office says he did not have his seat belt fastened.
