Richard Thomas boasted about selling steroids to professional baseball, hockey and football players, saying, "You name the sport, and I've sold steroids to athletes who play it," the Polk County Sheriff's Office said.
Authorities said Thomas didn't name specific players, and they have no evidence he sold to members of those teams.
Investigators who searched Thomas' house in Lakeland on Tuesday recovered thousands of anabolic steroid pills, injectable liquids and syringes with an estimated wholesale value of $100,000, said Carrie Eleazer, a spokeswoman with the sheriff's office. They also found several weapons, including loaded semiautomatic handguns.
Thomas and his wife, Sandra, were charged Tuesday with several counts of possession of illegal steroids, firearms, and maintaining a dwelling for drug use. Sheriff's records did not list an attorney.
Capitals players passed three rounds of drug tests during each of the past two seasons, and neither the team nor officials from the National Hockey League had reason to believe Thomas's claims, the league and the team said in a joint release Wednesday.
A spokesman for Major League Baseball, which also randomly tests for steroids, said the organization is looking into the matter. Nationals president Stan Kasten said he had been in touch with MLB and didn't have any cause for concern.
"For now, the story is what it is," he said in a conference call. "I don't know anything more than that."
Immigration and Customs Enforcement officials said they received a tip from Philadelphia about a drug deal in Lakeland and notified local narcotics detectives, reports CBS affiliate WTSP in Tampa.
Thomas told detectives he imported steroids from all around the world, including Iran, Pakistan, Slovakia, Russia, China, Turkey, Spain, Mexico and Germany. The sheriff's office said both Thomas and his wife were semiprofessional body builders, and that he claimed to be the largest steroids dealer in central Florida.
"He was very boastful," Eleazer said.
Thomas' mother told detectives the suspect was introduced to steroids by his father. When asked about steroids, Thomas told investigators, "It's all I've ever known," according to the sheriff's office.
