On the evening of December 10, 2022, 18-year-old Kaiden Michael Castaneda was found dead inside a home in the 1500 block of Evanston Street in Aurora, Colorado. Family members who entered the house around 7 p.m. discovered Kaiden and two other residents, 18-year-old Marisol Espindola and 41-year-old Estancia Martinez, each suffering apparent gunshot wounds. A welfare check earlier that day had brought Aurora police to the residence at about 5:15 p.m.; officers did not enter after seeing no signs of forced entry or anything suspicious.

Investigators identified a suspect who had been at the scene and known to the victims. By the next morning, a 21-year-old man, Christopher Martinez, had been arrested and charged with multiple counts of murder. Court filings later indicated Kaiden was Christopher Martinez’s brother. Few public details remain about motive or what occurred inside the home that evening.

If anyone knew Kaiden, his routines, or was in the Willow Park neighborhood that night, please share information that could help piece together what happened.
