EL PASO COUNTY, Colo. -- The El Paso County Sheriff’s Office is searching for a person of interest in the deaths of two teenagers earlier this month.

Investigators want to talk with 18-year-old Diego Carlos Chacon about the deaths of Natalie Partida, 16, and Derek Greer, 15.

Authorities say Chacon also goes by the nickname Casper. The sheriff's office believes he might have information that is important to the investigation.

Greer and Partida were found dead along the shoulder of Old Pueblo Road just south of Hanover Road near Fountain on March 12.

On Monday, the sheriff's office arrested Gustavo Marquez, 19, as a suspect in the case.

Marquez was arrested less than a month before the deaths of the teens for allegedly attacking and trying to kidnap a woman.

Anyone with information on Chacon or the case is asked to call the sheriff's office at 719-390-5555.
