Police are investigating an accident where a man rammed his car into a semi after threatening suicide. It began late Thursday afternoon near Iowa City when the Johnson County Sheriff’s office received a 9-1-1 call from a woman who said she and her daughter were dropped off by her husband, who told her he was going to Lake Macbride to commit suicide.

The woman gave authorities a description of the vehicle, which was spotted by a deputy who gave chase. The man sped up and started driving erratically, until he hit the rear of a semi. The man had to be extricated from the care. He was taken to the University Hospitals in Iowa City for treatment.
