Mark Calvin was 20 when he was fatally shot on October 6, 2019, in the 5800 block of Martin Luther King Boulevard in Houston. Described as outgoing, caring and active as a youth leader at his church, he had planned to attend Jarvis Christian College the following spring. His family noted his impact on the community, and his donated organs reportedly saved five local lives.

The shooting happened when a group of armed people fired into a crowded parking lot. Mark was killed and a 20-year-old woman, Brooklyn Rouse, suffered a gunshot wound to the head and survived after being hospitalized. The investigation identified four people who were taken into custody: Damond Terrell Diggs, 20, and Demetrick Reese Rogers, 20, were charged with murder; Keionta Mitchell, 20, was charged with felony deadly conduct for discharging a firearm; and a 16-year-old male was charged with felony deadly conduct and referred to juvenile probation authorities.

Are there details about the scene or witnesses that haven’t been reported that could help clarify what happened that night?
