Affidavit: Suspect in teen double homicide arrested for assault, attempted kidnapping only weeks earlier

The man accused of killing two teens was arrested on attempted kidnapping and assault charges just weeks before, according to court papers obtained by 11 News.

The El Paso County announced Monday that they had arrested Gustavo Marquez, 19, in connection to the deaths of 15-year-old Derek Greer and 16-year-old Natalie Partida. He was booked into the El Paso County jail Sunday night, exactly one week after Derek and Natalie's bodies were discovered along Old Pueblo Road near Hanover Road in Fountain.

The sheriff's office is calling the teens' deaths a double homicide.

The arrest affidavit for the deaths remains sealed at the time of this writing, but according to the affidavit for the February 24 arrest, Marquez is accused of trying to force an unnamed woman into a vehicle against her will, at one grabbing her by the throat and trying to drag her into the car. The affidavit states that at one point, after releasing the victim's throat, he started bending her pinkies back, then shoved her to the ground and pinned her.

Marquez is facing second-degree attempted kidnapping, second-degree assault-strangulation, harassment, domestic violence and child abuse charges. His child was reportedly present at the time.

He now also faces two charges of first-degree murder, kidnapping, aggravated robbery, and one charge of child abuse resulting in death for the double homicide.
