LOUISVILLE, Ky. — Jurors on the Roger Burdette trial heard more testimony and saw even more evidence in the case Thursday. 

Blood work completed after Roger Burdette crashed into Louisville Metro Police Department Detective Deidre Mengedoht’s cruiser showed a therapeutic concentration of a pain killer in his system. 

Toxicology expert Dr. James Davis reviewed reports and exams of Burdette’s blood work from the day of the crash. 

The reports said hydrocodone and clonazepam an anti-anxiety medication, were found n Burdette’s system. 

Davis said the drugs can make a person sleepy, impact critical judgment and slow their reaction even at therapeutic levels. 

“If this medicine is in your blood at a therapeutic concentration that does not mean that you are safe to perform that complex task. Therapeutic just means it’s having a therapeutic effect but it can also be having those negative effects as well,” says Davis. 

Davis calculated that the clonazepam was taken a day before the crash but says there is no information to determine when he took the pain killer, hydrocodone.

A traffic accident reconstructionist testified that he found no issues that would have prevented safe operation of the truck.   

Cellphone experts also took the stand confirming Burdette’s phone use based on pings from cell towers.

The jury also heard from an undercover Kentucky State Police detective. To protect his identity for his job, Spectrum News 1 is not identifying him by name.  That detective testified forensic software showed that Burdette unlocked his phone at 2:11 p.m. and an adult video played on the phone's screen until the internet app was closed at 2:20 p.m. 

According to testimony from witnesses and authorities, the crash happened around 2:15 p.m.

Burdette’s attorney questioned the ability to alter information using that software. 

Testimony resumes Friday in the case. The trial began Monday, Oct. 27 and a jury is made up of nine women and five men.
