Charges dropped against Parx trainer Felissa Dunn after investigation faults investigators

Charges against Parx trainer Felissa Dunn were dropped after an internal investigation found that one or more Pennsylvania State Horse Racing Commission investigators made material misstatements of fact, unraveling a possession case that had carried the kind of weight that can end a training career.

The original allegation centered on syringes investigators said they found in Dunn’s tack room and on a barn windowsill, though the items were not fitted with needles. Testing later reportedly turned up traces of two banned substances, which made the case more serious on paper, but the defense had long questioned the chain of custody and argued the matter never should have advanced with Dunn’s clean record at stake.

HIWU’s case portal now lists Dunn’s matter as a resolved case, with a controlled date of resolution of May 19, 2026 and a date of event of May 27, 2025. It identifies the alleged violation as Rule 3214(a), possession of a banned substance, and shows how central the agency’s records system has become in medication-enforcement disputes. HIWU says it publicly posts covered persons, covered horses and the rules allegedly violated, and it says its Internal Adjudication Panel hears controlled medication cases while state stewards are barred from participating in cases that originate in their own state of employment.

That structure matters because the Dunn case now stands as a test of what happens when the people bringing the charge are themselves found to have misstated key facts. A process meant to protect racing’s integrity instead raised questions about whether the initial evidence was handled carefully enough to justify the severity of the accusation.

The timing also gives the decision extra institutional heft in Pennsylvania. Tom Chuckas, the director of Thoroughbred horse racing at the Pennsylvania Department of Agriculture, and two other racing officials, Tony Salerno and Jason Clouser, were no longer employed by the Commonwealth, adding another layer of turbulence around the state’s racing oversight.

Dunn’s profile at Parx made the reversal even more notable. Parx Racing had recently said she trained and owned Kentucky Outlaw, a stakes winner, and quoted Dunn calling him "the nicest horse I’ve ever trained." For trainers across the backstretch, the case now reads as a warning as much as a reprieve: enforcement still has teeth, but the people wielding it will be judged on whether they get the facts right before a horseman’s livelihood is put on the line.
