A man accused of sexually abusing three minor children while in a position of trust pleaded not guilty to all charges Thursday in Albany County District Court.

Stephen James Calderon, 31, is charged with 11 counts of sexual abuse of a minor in the first degree. He could face up to 550 years in prison and $110,000 in fines if convicted on all counts.

Calderon’s trial is set to begin July 7.

Defense attorney Ian Sandefer said in court Thursday that Calderon plans to enter a guilty plea rather than let the matter go to trial. Judge Jeffrey Donnell told Sandefer to request a change of plea hearing when ready.

Calderon is currently in the custody of the Department of Corrections -- he was sentenced to prison for crimes in Converse County similar to those alleged in Albany County. According to Converse County District Court documents, Calderon pleaded guilty to four counts of sexual abuse of a minor in the first degree Oct. 15.

District Court Judge John C. Brooks sentenced Calderon Jan. 21 to 30 to 50 years in prison on each of two counts, with those sentences to be served concurrently.

Calderon was also given a suspended sentence of 25 to 50 years in lieu of 45 to 50 years of supervised probation on each of two other counts, to be served concurrently with each other but consecutive to the imposed prison term -- meaning Calderon will serve 30 to 50 years in prison before being released to serve 45 to 50 years on supervised probation.

Calderon was originally charged with 16 sex crimes in Converse County and entered the four guilty pleas as part of an agreement with prosecution in an effort to avoid trial.

An affidavit filed by a Laramie Police Department detective says a sergeant from the Converse County Sheriff’s office contacted the LPD detective Sept. 2, 2014 and said the Wyoming Division of Criminal Investigation’s Internet Crimes Against Children unit found Calderon created and shared child pornography in Douglas and Laramie.

According to the affidavit, Calderon admitted to a DCI special agent that he had illegal sexual encounters with a minor child under the age of 10 every other day for over a year. Calderon reportedly admitted to taking pictures and videos of some crimes, and said the pattern began with “special cuddle time” at a residence in Laramie.

Court documents say Calderon also described sex crimes against two other victims under the age of 16.
