Amos Dean Roberto Martinez, 25, was found dead on the front porch of a West 21st Street home in the Hyde Park neighborhood of Pueblo, Colorado, on the morning of April 3, 2025. Responding officers discovered Amos unresponsive with what appeared to be gunshot wounds; he was pronounced dead at the scene. He was born in Albuquerque, New Mexico.

Investigation quickly focused on a younger brother. Police arrested 19-year-old Andrew Martinez on suspicion of first-degree murder and booked him into the Pueblo County jail on a $1 million cash-only bond. Family members told police there had been ongoing conflict between the brothers. A sister reported hearing gunshots and later waking to another sister’s screams; the older sister found the front door ajar, blood on the doorknob, and Amos outside. Officers noted Andrew was wearing a tan jacket with bloodstains and family said he had worn the same clothes the previous evening. A small handgun that had belonged to a late husband of one sister was reported to be a weapon Andrew was supposed to have disposed of. Andrew declined to speak without counsel.

Does anyone have information about the Hyde Park neighborhood or the Martinez family that could help investigators?
