1,200 pounds of marijuana and 2 pounds of cocaine are missing from the evidence room of the Volusia County Sheriff's Department in Florida.

Timothy W. Wallace, 47, the former evidence manager, was arrested and charged with conspiracy to traffic in cocaine and marijuana. He was released on $300,000 bail and could face up to 30 years in prison if convicted.

Here's how it was discovered:

The Daytona Beach News Journal reports: Volusia County sheriff's investigators seized bricks of marijuana during several drug busts. Then they seized the marijuana again. It's the first time Florida law enforcement officials have investigated a case where seized drugs were put back on the street, they say. Sheriff's officials learned during the criminal investigation into the theft of half a million dollars' worth of drugs from their evidence compound that they seized the same narcotics more than once.
