On January 20, 2010, 32-year-old Richard Perez was killed in a violent incident at a residence in the 2300 block of Stair Street in Southwest Detroit. Officers who responded that winter day found Perez deceased; the Detroit Police Department classified the death as a criminal homicide and processed the scene.

Perez is described as a Black/African American male. Detectives investigated and entered the case into city and national violent crime databases, but the initial inquiry did not produce an arrest. Public cold case records show the investigation remains open and unresolved, with no suspects named.

Anyone who knew Perez, was in the Stair Street area that January, or has information that could help explain what happened is asked to come forward.
