On the night of January 13, 2018, 23-year-old Cahla Richardson and her 34-year-old partner Justin Flores were shot and killed inside their Robinwood Street home in Pontiac, Michigan. The couple, who had three children, were wounded around 11 p.m. after a planned robbery tied to a marijuana deal; both were found with multiple gunshot wounds and pronounced dead at the scene. Two young children and another man in the house were unharmed.

Police identified and arrested three suspects the next morning: 21-year-old Austin Ray Cooper and two 17-year-olds, Jordan Garcia‑Tinoco and Giovanni Kijuan McCaa. Authorities say the arrests followed an investigation that recovered a semi-automatic handgun believed used in the killings and concluded the marijuana transaction had been orchestrated as a robbery. Court proceedings resulted in convictions and prison terms for the defendants, with Garcia‑Tinoco identified as the shooter at trial.
