ST. LOUIS • A former St. Louis Fire Department paramedic pleaded guilty to charges of persuading three minors to have sex with him between June 2010 and March 2011, officials said Monday.

Noah Seth Bledsoe, 32, of the 1600 block of Lucas Avenue in St. Louis, was charged Dec. 8 with one count of attempting to coerce a minor to engage in sexual activities, one count of coercing a minor into sexual activities and one count of transporting a minor over state lines with the intent to engage in sexual activity.

Bledsoe also faces state charges of felony statutory sodomy, misdemeanor sexual misconduct and supplying alcohol to a minor for a series of interactions with a 16-year-old boy between December 2010 and February 2011. A court hearing scheduled for Jan. 3 was postponed due to the federal charges, according to court records.

The federal charges carry a possible sentence of 10 years to life in prison and/or fines of up to $250,000. Sentencing is scheduled for May 10.
