This is the story I received from a few witnesses on the scene.
The tall brown gentleman, Mr Woolery was the previous property manager and lives in the complex. The security guards along with the one who was killed were told by the new property manager not to open the gate for Mr.Woolery because he has not paid his agreed portion of maintenance costs.
The gate not being opened by the guards have a source of many arguments between Mr. Woolery and the guards and things escalated yesterday resulting in Mr. Woolery and the said security almost coming to blows.
Today , it is said that Mr. Woolery brought two men with him to confront the security guard and the men pulled the security guard into the guardhouse and beat him allegedly under Mr.Woolery’s instructions. This is why the video shows chaos around the shooting.
The said security guard who was beaten did try to disarm Mr Woolery when his back was turned but this is no random attack. The security guards have complained about Mr Woolery’s treatment towards them after following managemnt’s instructions.
