September 7, 2022
— Today, 17th Judicial District Attorney Brian Mason is announcing the 25-year Department of Corrections sentence for Marcos Gutierrez, 24, following his guilty plea to Second-Degree Murder in Adams County District Court on June 24, 2022.
On April 11, 2020, Marcos Gutierrez was using LSD inside of an apartment along North Peoria Street in Aurora. Witnesses inside the apartment said Gutierrez began to seek out firearms and other weapons including knives. The defendant eventually located a knife in the kitchen. As his girlfriend exited the bathroom, Gutierrez came up behind her and slit her throat with the knife.
One of the witnesses inside of the apartment heard the victim ask the defendant, "Why did you do that? What did you do?" She then fell to the ground and later died at a local hospital.
On June 24, 2022, Gutierrez pleaded guilty to:
- Second-Degree Murder (F2)
On September 7, 2022, an Adams County District Court Judge sentenced Gutierrez to 25 years in the Department of Corrections.
"This was a horrific and gruesome crime", said District Attorney Brian Mason. "Our hearts go out to the victim and her family. I hope this sentence today will give them some measure of closure and peace. I appreciate the work of the Aurora Police Department and my team at the DA's Office in seeking justice in this case."
Deputy District Attorney Ashley Munoz and Chief Deputy District Attorney Ally Baber led the prosecution of this case.
