An Aurora man will spend 40 years in prison after pleading guilty to charges related to possessing thousands of images and videos of child sexual abuse, including images and videos of himself abusing children.
Aaron Marshall Mocalkins, 31, was sentenced in Arapahoe County District Court on Friday after pleading guilty to three felony counts of sexual exploitation of a child.
Eighteen other counts — including child sex assault and animal cruelty — were dismissed by prosecutors as part of the plea agreement, according to court records.
Mocalkins was arrested in September 2024 after police linked him to a tip from the National Center for Missing and Exploited Children.
Investigators seized his phones and other electronic devices and found thousands of images and videos depicting child sexual abuse, including an infant victim, according to the 18th Judicial District Attorney’s Office.
Mocalkins also had many photos and videos that showed him sexually abusing children, an infant and a dog, the DA’s office said.
“These crimes leave deep and lasting scars, and while no prison term can undo that harm, this sentence holds the defendant accountable and affirms our unwavering commitment to protecting children and delivering justice,” District Attorney Amy Padden said in a statement.
Mocalkins was represented by the Office of the State Public Defender, which does not comment on criminal cases.
