Two state troopers put on leave in conjunction with the investigation of former trooper Franklin Ryle Jr. no longer work for the Wyoming Highway Patrol, the agency's top official said Tuesday.

Col. Sam Powell said he couldn't go into further details regarding the departures of Adam Longo and Devan Henderson because it was a personnel matter. However, he did say the patrol is swiftly working to fill the vacancies with two recruits who've already accepted positions with the agency.

Longo and Henderson had been stationed in Casper.

"We are going to move as quickly as we can to fill those vacancies," Powell said.

Longo had been on leave since Feb. 5. Henderson was put on leave Feb. 19.

The men were unavailable for comment Tuesday. Neither has a listed phone number.

In May, the patrol disclosed that both men were on paid leave. At that time, Powell did not explain exactly what prompted the move, other than to say it was done in conjunction with the Ryle investigation.

Ryle, a former Douglas-based trooper, pleaded guilty last month to federal civil rights charges. He admitted to arresting a Wal-Mart truck driver in January as part of a scheme to kill the driver and stage a crash with his patrol vehicle in order to collect a financial settlement.

Neither Henderson nor Longo has been arrested or charged with any crime.

Henderson told investigators he smuggled steroids from Mexico into the United States in 2003 or 2004, according to an FBI affidavit detailing the Ryle investigation. He claimed he and Ryle used the steroids as part of a body-building program.

Ryle was also accused of soliciting Henderson to participate in his scheme.

Henderson told an FBI agent he did not report Ryle to anyone because he wasn't sure Ryle was serious and because he didn't want to be considered a "rat" if the statements proved false, according to the affidavit.

Longo is not mentioned in any of the court documents.

Ryle, who was not indicted on any charges related to the steroid allegations, is awaiting sentencing next month.
