Former trooper pleads guilty to possession of steroids.

A former state trooper will likely avoid jail time after admitting in court Tuesday to possessing anabolic steroids.

Asked by a judge how he wanted to plead to the charge of possession of a controlled substance, Adam Longo replied, "Your honor, I'm guilty."

Longo's name surfaced during a Wyoming Division of Criminal Investigation probe of Franklin Ryle Jr., a former state trooper accused of kidnapping a Wal-Mart truck driver. During that investigation, authorities discovered anabolic steroids in Ryle's desk, according to a police affidavit.

In February, Longo walked into the office of Col. Sam Powell, the head of the Wyoming Highway Patrol, and admitted that he had used steroids during the previous 18 months and given some to Ryle.

According to police, Longo said he purchased the steroids at a Casper gym.

Speaking after Longo's arraignment Tuesday, District Attorney Michael Blonigen said several factors played into the plea agreement. Longo had no criminal record, and the anabolic steroids he admitted to having -- more than 0.3 grams of Cypiogen in liquid form -- was for personal use, Blonigen said.
