An Iowa man is in custody facing attempted murder charges after allegedly opening fire on multiple vehicles along Interstate 35 on Tuesday, authorities reported.

The suspect, identified as 42-year-old Christopher Lee Johnson of Waterloo, Iowa, was apprehended by law enforcement after a pursuit that ended near the Minnesota border. According to initial reports, Johnson told investigators that he "had to kill people today."

The incident began around 10:30 a.m. when law enforcement received multiple calls reporting a driver firing shots at other vehicles on I-35 northbound near Clear Lake, Iowa. Witnesses described a sedan swerving and shooting at other cars, causing panic among drivers on the busy interstate.

Authorities quickly identified Johnson's vehicle and initiated a pursuit. The chase continued for several miles before Johnson's vehicle was stopped and he was taken into custody without further incident. No serious injuries were reported among the targeted motorists, though several vehicles sustained damage from gunfire.

Investigators are currently working to determine a motive for the shootings. Johnson has been charged with multiple counts of attempted murder and other related offenses. The investigation is ongoing, with state and local law enforcement agencies collaborating on the case.

This incident has raised concerns about public safety on major roadways and the unpredictable nature of such violent acts. Officials are reviewing the circumstances surrounding the event and the suspect's background to understand how such an attack could occur.

Further details are expected to be released as the investigation progresses. The interstate was temporarily closed in both directions to allow for crime scene investigation and vehicle recovery, causing significant traffic delays in the area.
