On November 9, 2024, at about 5:50 p.m. McKinney police responded to multiple 911 calls reporting gunfire near Chestnut Street and Colorado Street. Officers found two male victims with gunshot wounds: 17-year-old Kajarryawn Mack and his 22-year-old brother, Lamarrya Ransem. Both were taken to local hospitals and died of their injuries.

In the days after the shooting police arrested three people: 21-year-old Roman Miguel Castillo and two juveniles. All three have been charged with capital murder; further identifying information about the juveniles has not been released because of Texas juvenile privacy laws. Authorities say the investigation into the motive is ongoing and have not released details about circumstances leading up to the incident. The department also stated there are no indications of additional suspects.

Community members provided first aid to the victims before emergency responders arrived, a response the McKinney Police Department described as important and compassionate. If anyone has information related to the case, contact Detective Robertson at [email protected].
