A Fort Carson soldier convicted of sexual assault on a child was sentenced Wednesday to 30 years to life in prison, according to the 4th Judicial District Attorney's Office.

Spc. Joe Alfred Garcia Jr. pleaded guilty in December to two counts of sexual assault on a child by a person in a position of trust.

He was arrested Oct. 2 after Boston Homeland Security investigators contacted Colorado Springs police for assistance in a child pornography ring involving Garcia and spanning multiple states.
