PENSACOLA, Fla. (AP) -- A Florida crime lab employee has resigned during an investigation into missing drug evidence that could compromise hundreds of cases.
Joseph Graves submitted a resignation letter Monday, two days after the agency announced the investigation.
The Florida Department of Law Enforcement confirmed the resignation of a chemist who is suspected of substituting non-prescription drugs for prescription painkillers. When The Associated Press asked for the suspect's resignation letter, the department released a copy of Graves' letter.
No one responded to a voice message left at a telephone number listed to a Joseph Graves, and no one answered a knock on the door of a house located at an address registered to that name. The State Attorney's Office identified his lawyer as Michael Griffith, who declined to comment when contacted by telephone.
