A 39-year-old Fort Carson sergeant first class pleaded not guilty this week to 438 charges tied to child sex crimes, including sexual assault and exploitation, rejecting a plea deal that would have dropped all but two counts against him. Marquez Parker entered his plea before an El Paso County judge on Monday, setting the sprawling case on a path toward an April trial.
According to The Gazette, Parker was initially arrested on allegations of possessing, producing and selling child sexual abuse material. In the months that followed, prosecutors added 62 more charges largely related to sexual assault, and later tacked on another 372 counts connected to child sexual abuse material, bringing the total to 438.
Prosecutors had offered Parker a deal to plead guilty to just two counts of sexual assault on a child while in a position of trust, with the remaining 436 counts to be dropped in exchange. Under that proposal, the station's report notes, Parker would have faced 30 to 40 years in prison along with mandatory parole ranging from 20 years to life. He did not take the deal.
Investigation Traces Back to a 2025 Tip
Court documents cited in the same report say Fountain police investigators began looking into Parker in early 2025 after receiving a tip from a nationwide agency. The investigation was later transferred to the Army's Criminal Investigation Division under department policy, and CID then asked Colorado Springs police to take the lead as the head agency of the Colorado Internet Crimes Against Children Task Force, per the article.
A search warrant allegedly recovered 28,000 items of child sexual abuse material, the outlet reported. It remains unclear how many victims are involved in the case, according to the same account.
Hearing Waived as Plea Talks Continued
Parker waived his preliminary hearing, which was meant to establish probable cause, even though prosecutors were prepared to call four law enforcement witnesses to the stand. His attorney, Joshua Lindley, advocated for waiving the hearing in hopes of renewed plea deal negotiations. Prosecutor Kelson Castain said discussions with Parker were ongoing as of Monday.
Judge Amy Cano set the case for trial in April, which could take up to three weeks. The next hearing is scheduled for March 15 to review pretrial motions. Court filings described in the same coverage indicate both lawyers requested a review of another judge's juror questionnaire, or the creation of a new one, to avoid potential bias.
Separate Allegation Involves Protection Order
Parker is also accused of violating a protection order issued after his arrest. Court records say he is accused of being around children at an eighth-grade graduation in May, which he had been ordered to avoid. None of the allegations in the case have been proven in court, and Parker has pleaded not guilty to all 438 charges.
Earlier reporting from CBS News Colorado described Parker as initially facing two felony charges for distribution and possession of child sexual exploitation material, a case that has since grown substantially as investigators continued their work. A January report from The Gazette put the count at 49 new charges at that point, including alleged incidents dating from October 2023 through February 2024, and noted that Colorado Springs police had confirmed the investigation remained active with CSPD as the lead agency.
