No one can be seen rendering aid to Crutcher until more than 2½ minutes after he was shot, which Tuell said after the news conference is also under investigation. Turnbough's dash cam video shows an officer apparently searching Crutcher's pockets and waistband for weapons or other contraband before starting first aid.

Attorney Scott Wood, who is representing Shelby, told the Tulsa World that the situation unfolded for nearly 2 minutes before the video footage began. Prior to the deadly encounter, Wood said no one was around when Shelby pulled up. The SUV was straddling the center line with its engine running and doors open, "so she isn't really sure what's going on," Wood said.

He said Crutcher repeatedly ignored Shelby's commands and didn't respond to her questions. Crutcher, he said, reached toward or into his pockets several times despite Shelby's telling him not to do so.

Wood said Shelby, who has completed drug recognition expert training, believed that Crutcher was acting like a person who might be under the influence of PCP.
