Meanwhile, Kelli Rogers, a resident of the suburb of Memphis in Arlington, testified that her wallet with an ID and credit card was stolen in 2022. Rogers said she was recently told that one of her credit cards was found in the car and that she didn't know about Nichols.

The officer who pulled Nichols up said they did this because he was reckless and driving, but they didn't know what was found in his car.

Prosecutor Hagerman asked Baker if he found out whether ID and credit card affected how TBI investigated the raid.

“It still has nothing to do with the seriousness of the case I was asked to investigate,” Baker said.

Zummach then asked Baker if there was reason to conclude that Nichols refused to arrest and wanted to leave the vehicle because he might have "evidence of crime in the car."

"Probably," Baker said.

Baker also testified that mushrooms containing hallucinogenic proteases were found in the car. Medical Examination Doctor Rose testified that Nichols has no hallucinogens in his system.
