After a follow-up investigation on the previous arrest of former Hardee County Sheriff’s Office Sergeant Mark McCoy, further information emerged and led to a second arrest.

On March 31, 2020, following his resignation, McCoy’s canine training drugs were turned back in to HCSO evidence for inspection while he was present. The Drug Enforcement Agency supplies each K-9 unit with a specific amount of different narcotics for the K-9’s to continuously train with, including cocaine, marijuana, methamphetamine and heroin. Upon further inspection of the narcotics turned in by McCoy, it was apparent several individual packages had been tampered with.

In April of 2020, the drugs were submitted to the Southeast Regional Drug Enforcement Agency Laboratory in Miami for testing and analysis. The results from the tests revealed the heroin and cocaine turned in by McCoy were less than one percent substance purity, meaning there was barely any trace of the original narcotics left in the packages. They were instead replaced with different substances matching the appearance of the original drugs.

Mark McCoy was arrested on August 4, 2020 and charged with three counts of destroying evidence / tampering with or fabricating physical evidence, possession of heroin and possession of cocaine. McCoy was originally arrested back in May for the purchase and possession of Oxycodone without a valid prescription.

“Mark was a valued and trusted employee of the sheriff’s office for nearly 15 years. This discovery is truly devastating to our agency and we want the community to know his individual actions do not reflect the integrity of his family or the Hardee County Sheriff’s Office. What he did was wrong and he will be prosecuted to the fullest extent of the law.” – Sheriff Arnold Lanier
