A 19-year-old man was arrested late Sunday in the deaths of two Colorado Springs teens, the El Paso County Sheriff's Office said Monday.
Gustavo Marquez was arrested on suspicion of two counts each of first-degree murder, second-degree kidnapping and aggravated robbery and one count of child abuse resulting in death, according to the Sheriff's Office.
Investigators suspect he killed Derek Benjamin Greer, 15, and Natalie Partida, 16, who were found dead March 12 on the shoulder of Old Pueblo Road in a rural part of the county. Derek was a freshman and Natalie was a sophomore at Coronado High School.
The El Paso County Coroner's Office ruled their deaths homicides, but has not said how they were killed, withholding details until after completion of an autopsy.
Marquez was arrested on one count of child abuse because only one of the teens was younger than 16 years old, said Jacqueline Kirby, a Sheriff's Office spokeswoman.
He remains in the El Paso County jail without bond, inmate records show.
Less than two weeks before the teens were found dead, Marquez bonded out of jail on separate charges, court records show. He was arrested by Fountain police Feb. 24 on suspicion of attempted second-degree kidnapping, attempted second-degree assault, third-degree assault and child abuse. He posted bond Feb. 27 and was in court March 8 for his first appearance.
Anyone with information is asked to call the Sheriff's Office tip line at 520-6666 or 520-7777.
