One person in the Oregon District at the time of the shooting told News Center 7 that he had dropped his cell phone and keys during the incident and that police was not letting him back in the district to grab his phone and keys.
Bowron explained that investigators were likely trying to keep anyone from accidentally tracking something into or out of the scene.
