Man sits in jail when drywall power is mistaken for cocaine

Cashe was already on probation for weed and coke charges from 2015, and cops say a field test at the scene came up positive for cocaine, while a drug-sniffing dog went wild for his auto.

"I know for a fact that it's drywall because I'm a handyman", Cashe told the TV station.

Karlos Cashe was pulled over in Oviedo for a routine traffic stop when the police officer said he noticed a white powder in the man's vehicle.

Three months later, a Florida Department of Law Enforcement lab report revealed no controlled substances were identified, and the charges were dropped.

When an officer saw white powder on his seat and floorboard, though, the situation became much more serious.

The Oviedo Police Department said it plans to reevaluate its field testing procedures. Cashe ended up spending a title of 90 days in the Seminole County Jail for a crime he was not guilty of.

The conference at the Fontainebleau Miami Beach has drawn 258 mayors, according to organizers. Clinton said mayors should step up to the plate and be ready to show results.

Because he was on probation for previous drug charges, his bond was denied.

When it finally did, the test confirmed what Cashe had been saying the whole time. The test confirmed that there were no drugs present in Cashe's vehicle at the time of his arrest.

He was released last week and hopes that the police will be more cautious in cases like his.

"I don't want this to happen to anybody else", he added. 'I said that continuously during the arrest stop'.

Oviedo police told Channel 9's Jeff Levkulich it will take a closer look at their drug test kits after drywall tested positive for cocaine. "There's no intent, when something comes back positive we take it, it's our probable cause and that's why we send to FDLE to confirm".

For example, some field tests use a chemical called cobalt thiocyanate that turns blue when it comes in contact with cocaine.
