How do you know that in the darkness, these officers, seeing a vehicle; -that is within the realm of a matching the description of the suspect vehicle (dark colored pickup), and had very recently been told that the suspect vehicle may have been spotted and heading their direction.
He was moving away from Torrance and distances/traffic could not have had him at both locations within the time frame of the shooting and the Torrance incident.
I was on my way to work listening to the news broadcasts as this was unfolding. They reported that the Torrance incident was "unrelated to the Dorner search"
Yes, I know the news media often gets it wrong, either intentionally or through ignorance, but they get their information from the PD and there would have been no reason for the news agencies to report that it was unrelated if it was not fed to them.
At the same time, the news was (correctly) reporting that the vehicle was a Gray Nissan Titan. The Caltrans freeway signs were reporting it as a Blue pickup.
Thankfully, the Torrance incident was the only police-involved shooting of a civilian. As on edge as all police agencies in SoCal were, this could have been very bad. It was bad enough that Dornan killed those he did.
