Terry Harris was 16 when he was shot and killed in the basement of a Des Moines house on June 9, 2015. The wound was at close range to the mouth. The shooter was not a stranger; investigators say the suspect and Harris were acquainted.

After more than a month without an arrest, tips and information obtained from social media helped lead authorities to a 17-year-old male who was already in custody on unrelated charges when arrested in connection with Harris’s death. Police allege the killing was motivated by robbery and charged the teenager with first-degree murder and first-degree robbery. Other people were in the house during the shooting, and their statements and other evidence were described as important to reconstructing what happened.

If anyone was in that Des Moines neighborhood on June 9, 2015, or has information about Terry Harris and the people who were at the house that day, please come forward.
