POLK COUNTY, Fla. -- A Winter Haven man whom police described as suicidal intentionally rammed two vehicles during a pursuit on U.S. Highway 27 before dying in a rollover crash initiated by deputies, according to the Polk County Sheriff's Office.

The PCSO said that the man died after being ejected from his vehicle during a rollover crash caused by a precision immobilization technique (PIT) performed by a deputy to stop him from crashing into other drivers.

The suspect, who has not been identified pending notification of next of kin, called the PCSO twice on Wednesday morning, saying he intended to kill himself and a deputy sheriff. On-Star technology enabled deputies to locate the suspect driving eastbound in a black Chevrolet pickup on Dundee Road approaching U.S. Highway 27. The truck hit stop sticks planted by the deputies, causing a flat tire.

The man then rammed the two vehicles, which sent at least one victim to the hospital with injuries, before a deputy who is trained in the PIT technique rammed the rear fender of the truck to stop him.

According to the report, the man not wearing a seatbelt and was thrown from his truck when it went off the roadway and rolled over. He was transported to Lakeland Health Regional Medical Center where he later died.

Deputies later found notes at the suspect's home indicating he intended to commit suicide.

The sheriff's office investigation is ongoing.
