MARION COUNTY, KY (WAVE) - Authorities said Wednesday they're not taking any chances in their search for Floyd Cook.
Cook is the career criminal accused of shooting and injuring an officer in Tennessee, then shooting at troopers in Kentucky over the weekend.
The search continues statewide, as well as in Tennessee.
Kentucky State Police is leading the investigation, along with the help of the FBI and U.S. Marshals.
Authorities have called the 62-year-old "armed ... extremely dangerous ... (and) desperate."
Crews found nothing in Marion County, where Cook once lived in a rural area.
KSP also is looking for 50-year-old Troy E. Wayne, whom they believe may be with him.
Cook's actions are affecting people across the state. Schools in Cumberland County canceled classes for the third day in a row after it was reported Cook was in the area Sunday. The district's superintendent, Dr. Kirk Biggerstaff, said he wasn't taking any chances.
Cook has a long criminal history that began in 1971, when he was convicted of raping a child in Marion County. He was released on parole in 1978, according to Department of Corrections records.
That same year, he was convicted of second-degree assault and was paroled in 1983, the records show. He violated his parole and landed back in prison in Boyle County. That's where he picked up two more felony convictions for second-degree assault and rioting.
In 1986, Cook was out again when he was arrested first-degree robbery and persistent felony offender charges. He was sentenced to 100 years, according to the DOC.
Two years later, Cook escaped from a maximum security prison and was recaptured two days later. During his escape, he was arrested and convicted on two more charges -- burglary and persistent felony offender. He was sentenced to an additional 20 years.
But in August 2009, Cook was paroled yet again. He was under supervision until Aug. 15 of this year, when he violated the terms of his supervision. There was an active parole violation warrant before the latest manhunt, the department said.
