A neighbor had called the Fort Worth Police Department’s non-emergency line and requested a wellness check when he noticed Jefferson’s front door open and the lights on. Dean and another officer responded to the call; Dean went to the back of the house, where he saw Jefferson’s silhouette in the window. He ordered her to show her hands and almost immediately fired a single shot.

Marquis Jefferson temporarily halted his daughter’s funeral last month because he felt he had been blocked from participating.The parties settled their dispute and the service was held later.
