Driver was wanted in Minnesota for the slaying of a Shoreview woman.
On the run from authorities seeking him in the shooting death of his estranged girlfriend, Clarence Henry was leading Illinois State Police on an 85 mile-per-hour chase.
Without slowing the car, the St. Louis Park man turned his gun on himself.
It was a dramatic end to the search for Henry, who was named a person of interest in the shooting death of Susan Levoir, 44, of Shoreview. St. Louis Park Police Chief John Luse said he is confident Henry shot Levoir.
Police say Levoir, who had recently ended her relationship with Henry, called a family member at 8 p.m. Tuesday to let them know she was dropping off some things at his apartment. Thirty minutes later, she told that relative to alert police if she didn't call within an hour.
She never made the call.
By the time police were contacted at 9 p.m., Levoir was dead of a gunshot wound.
On Wednesday, police said they were looking for Henry as a person of interest in connection with the slaying and asked for help finding him,
At 4 p.m. Wednesday an Illinois State Trooper spotted Henry's red Chevy Cavalier at the Willow Creek Rest Stop along Interstate 39 in northern Illinois, between Rockford and Interstate 80. While the trooper waited for backup, Henry left the rest stop, and troopers pursued him southbound, said Trooper Melissa Randick.
The brief chase went about three miles and reached speeds of 85 miles per hour before Henry shot himself while driving, causing his car to cross the median and northbound lanes before coming to rest on the other side of the Interstate.
"Luckily, no one else was involved in an accident. It's quite surprising," Randick said.
According to police, Henry had a criminal history dating back more than 20 years in St. Louis Park and surrounding communities, including domestic violence. There were no reported disputes between Levoir and Henry. Court records show charges for possession a weapon without a permit, terroristic threats and fleeing a police officer filed in 1988. The terroristic threats charge was later dismissed.
