Six months after licensing a convicted felon and drug dealer to work as an emergency medical technician in Iowa, the state has revoked the man’s license.

According to the Iowa Bureau of Emergency Medical Services and Trauma, Adam Doty was fired from the Sioux City Fire and Rescue Department on July 29, 2024, due to his alleged off-duty use of methamphetamine on July 25.

The bureau then made what it calls “numerous attempts to contact” Doty before learning he was incarcerated in a federal prison in Minnesota on drug charges.

Four weeks ago, the office charged Doty with habitual intoxication or drug addiction, excessive use of medication likely to impair an emergency medical provider’s ability to practice with reasonable skill or safety, and willful or repeated violations of EMS regulations in Iowa. The bureau then revoked Doty’s license, effective Oct. 23.

Sioux City Fire and Rescue representatives could not be reached for comment Monday.

Court records show Doty had been arrested several times before he was licensed by the state as an EMT and employed by the city.

In 2007, Doty was convicted of possession of marijuana on one occasion and was convicted twice of first-offense driving while intoxicated. In 2009, he was convicted of felony drug distribution, and in 2010, his probation on that charge was revoked after he admitted to a South Dakota arrest on a drug charge and seven separate parole violations .

In 2017, Doty was convicted of third-felony possession of marijuana, and a short time later was indicted by a federal grand jury on charges of conspiracy to distribute methamphetamine. In April 2018, he was sentenced to 91 months in prison, with federal prosecutors saying Doty had been a “methamphetamine dealer in the Sioux City area” who bought and resold “multi-ounce quantities of methamphetamine.”

At some point, Doty was released from prison on supervised parole, and in April 2024, while still on parole, he was certified as an EMT by the Iowa Bureau of Emergency Medical and Trauma Services.

According to the city of Sioux City’s human resources office, Doty was hired on June 15, 2024, at which time he began working for Sioux City Fire and Rescue as a firefighter and EMT.

Around that time, for reasons detailed only in sealed court records, Doty’s parole was revoked. He was fired by the city in July and ordered in August to serve eight months in prison, followed by two years of supervised release.
