 And a person familiar with the investigation who was not allowed to speak publicly did tell NPR that at least one potentially explosive device was found in Crooks' car at the rally site. Potentially explosive device. Okay, we'll wait for more details on that. Now, I'm thinking about the shooter himself. He's 20 years old. He's a high school graduate. He's living with his parents. Did he have a job? He did. Crooks was working at a nursing home in town. It's the Bethel Park Skilled Nursing and Rehabilitation Center.
