The VT Shooting...unanswered questions.

This needs no intro paragraph; everyone knows the story. But I have many questions about this I would like answered. 1. How many shots were fired at Officer Crouse? 1, 3, 10? How many times was he hit? No official answer. And where was Officer Crouse hit? These are standard details provided in any run-of-the-mill crime story, yet absent here. 2. What was the make and model of the car Officer Crouse had pulled over? I have looked at pics and videos from "breaking news" sources, and I see no car in front of his cruiser. 3. Reports say Officer Crouse was shot "in front of witnesses." But a witness also said later that when backup arrived, Officer Crouse "fell out of the car when they opened the door." Did NO ONE even approach his cruiser to offer aid if they had just seen him get shot? 4. Was the pulled-over driver the person who called 911? And what was the offense for which the driver had been pulled over? 5. Why would Ross Ashley drive his own car less than 2 miles to steal another person's car to drive less than 20 miles? Why not just drive the extra 12 miles to Blacksburg? 6. If Ross Ashley just wanted to kill at random, why was he so subdued and focused in the Radford real estate office, and why did he spare those 2 ladies? Wouldn't that suggest he was "on a mission?", i.e. this was a mean toward his ultimate goal. 7. When Ross Ashley entered the real estate office, armed, he didn't go in with a drawn gun, he specifically, and politely, asked for "her" and drew the gun later. He asked specifically for the keys to "her" vehicle. Why? And she says she had never met him...so how did he know the Mercedes was "hers?" 8. Ross Ashley made no attempt to ditch the stolen Mercedes, instead he left it parked in perfect, returnable condition on the VT campus. Wouldn't that suggest that auto theft wasn't the motive? And wouldn't it also suggest that the VT campus was his specific destination? 9. Ross Ashley had the Mercedes available on the campus to drive away. Why, 30 minutes later, was he still lingering? Why didn't he just drive away? 10. If Ross Ashley had just killed a police officer in cold blood "in front of witnesses" and "with no apparent motive" why was he so terrified at the sight of another officer that he would kill himself in less time than it took that officer to turn his car around? This story is FAR from over. NOTHING is adding up....there is obviously a very specific motive here. This was NOT random. Eric
