Former State trooper admits selling steroids.

Three days before his scheduled trial, former Department of Public Safety Trooper Jeffery Jerman pleaded guilty Monday to three charges of selling steroids to a police informant from his patrol car in September 2009.

Jerman, who was fired over his arrest after nine years as a trooper, faces up to two years in jail on each count when sentenced March 11 by state District Court Judge Rex Emerson.

A Boerne resident, Jerman declined comment as he left the courtroom.

He went to trial here on the same charges in November, but a mistrial was declared before testimony could begin after a juror told the judge that she couldn't be impartial.

Jerman also faces a federal charge of conspiring to distribute steroids, which carries a maximum sentence of five years. Trial is set for Feb. 28 in that case in U.S. District Court in San Antonio.
