DENISON, Texas -- A man who claimed he was high on antibiotics while evading arrest is headed to prison.
Dash cam footage from November shows Gary Cummings blowing through a stop sign near downtown Denison.
When police try to pull him over, the 49-year-old drives a few more blocks then jumps out of his moving pickup truck.
The foot pursuit goes out of frame but you can hear the struggle between Cummings and the officer.
Cummings told investigators he thought someone was trying to kill him and claimed he was paranoid because he was high on antibiotics.
"At one point, he picked up an officer who was 255 lbs. and over 6 feet tall and threw him onto his back," Prosecutor Brett Smith said. "We and the jury believe that it was a result of meth, not antibiotics."
A jury found Cummings guilty of evading arrest with a motor vehicle and was sentenced to 30 years in prison. He will be eligible for parole in 15 years.
"We had a doctor testify that in his 33 years of experience, he had never had anyone report hallucinations from antibiotics," Smith said.
This isn't Cummings first run in with the law, he has over 15 felony convictions in Grayson County.
"The only time Cummings is not committing a crime is when he is locked up," Smith said. "That is the only way I can describe the defendant."
