In July 2009, the Division of Pari-Mutuel Wagering received three anonymous complaints. "He... come[s] late at nights when no one is there to give his 'vitamins,'" began a letter from someone who said he worked for the trainer. "He carries a black briefcase and sometimes he takes the needles out of it to inject the horses."
The letter continued, "If you get someone to search the car or truck, you will find the drugs there... That is the real stuff that he gives the horses to make them run faster or hide their pain so they could run on race days."
Another letter claimed, "I have known this young man since his teenage years and ever since then, he was filled with greed to win races." A third accused Ziadie of avoiding suspensions by racing his horses under other trainers' names.
One of Ziadie's employees began cooperating with Calder. The unnamed assistant gave the track's security manager, Steve Diamond, hypodermic syringes full of drugs that he claimed Ziadie had told him to inject into various horses shortly before their races.
"I hope I am not placed in danger and that my name is not revealed," the informant wrote, adding that Ziadie often killed barn pigeons with a shotgun. "[If] he finds out... he is crazy and capable of killing me or paying someone else to do it for him."
On August 20, 2009 — five years after Calder was first informed of the trainer's drug violations — Ziadie was finally banned from the track. Calder officials gave him 72 hours to remove his 50 horses.
Incredibly, state regulators closed their case against Ziadie a few months later when the informant abruptly disappeared.
