Patrick Ohien, 51, was shot and killed outside a Conoco convenience store at 13102 Bissonnet near Synott in southwest Harris County, Houston, on November 6, 2011. Investigators say he was drinking with a group of men when two suspects approached and attempted a robbery at gunpoint; a struggle followed and Ohien was shot in the chest. He was taken to Southwest Memorial Hermann Hospital and died shortly after arrival.

Police identified two suspects as Tyreon Young, 17, and Patrick Sharard Guillory, 22. Guillory was taken into custody and held without bail; Young was at large for some time. A witness later told investigators Young contacted them the day after the shooting to ensure they would not disclose details, and that Young had shot Ohien when the victim tried to take the gun. Another person who drove the suspects said he heard them planning the robbery and that Guillory had shown him a revolver beforehand.

Does anyone have information about that night or remember seeing activity near the Bissonnet Conoco on November 6, 2011?
