>>> here at tom clements home in colorado just before 9:00 p.m . tuesday night, witnesses described seeing a black lincoln or cadillac idling outside the victim's home a few minutes before the shooting and authorities called it a vehicle of interest. late this morning 500 miles away in texas , a deputy tried to pull over a man heading south in a black cadillac with colorado license plates, a routine traffic violation . the driver of the car responded by opening fire on the deputy shooting him and hitting him three times before taking off. he then sped in and out of traffic at 100 miles an hour shooting out the window of his car at the officers following him in the high speed chase . ultimately he crashed the car into an 18-wheeler. he got out, fired on the officers again, the officers returned fire and he was hit. tonight, colorado investigators are on the way to texas to determine whether that man in the high speed chase might be linked to the killing of tom kle clements , the colorado prisons chief. the man is still unidentified, in a fort worth popt and finger printed him and basically legally dead and on life support machines after being shot in the head in the shootout. the deputy he shot was wearing a bullet proof vest and also shot in the head and the deputy was shot in a grazing wound and expected to survive. colorado investigators will be working alongside the texas rangers . because he was the prisons chief in colorado , investigations of anything that happens within texas prison systems will be involved in the investigation now on-scene this afternoon as well making phone calls . colorado 's governor has reacted to all this by saying, quote, we don't know yet exactly whether this is the guy. there is some indication. i hope it is. of course, the overall story here is still that we do not know what the motive might be for the killing of tom clements , whether it was related to his job running the prisons or to colorado state politics more broadly or to neither of those issues. tuesday night's shooting happened hours before the colorado governor was due to sign into law the hotly contested new gun reformulation that state lawmakers passed last week. governor hickenlooper announced the details of the murder, of the state's prison director at 8:30 a.m . local time yesterday, and then went on as scheduled later that morning to sign into law his state's new background checks legislation and a new state limit on extended magazines for ammunition and semiautomatic rifles and handguns. law enforcement sources have said there -- have not said there is any reason to connect the killing of states prisons chief to his work in the prisons or broader political issues in colorado . still, though, in response to the murder, security has been upped, both for the governor himself and for other members of the state's cabinet. now, one possible connection between tom clements ' work and potentially -- a potential motive for his murder, one potential connection, at least, getting a lot of attention in the colorado press is tom clements ' direct involvement in the case of a man named ham adean al turkey almost seven years ago convicted of keeping a woman as a virtual slave in his house, sexually assaulting her. last week, tom clements wrote to him personally to let him know that he, tom clements , was denying his request to serve out the remainder of his sentence in saudi arabia . which is mr. al-turki's home country . today they moved him to solitary con fimt for his own protection because of the media attention on his case after mr. clements ' murder. officials stress the decision was not directly related to the clements murder investigation, they say that mr. al-turki was not being punished. they say it is simply because of the publicity. it is very disturbing to have a public official murdered ever. even more unsettling, when it happens so inexplicably. when you don't know why. there is also the possibility the killing was entirely unrelated to his status as a public official . it could just have been either personal or completely random. we learned today that colorado deputies, for example, are looking into a possible link to a craigslist ad that tom clements posted on the day of the killing. they're investigating whether the person who shot him might have gone to his home on the pretense of buying the bicycle that was posted in the ad. the el paso county sheriff's office is reportedly checking mr. clements ' cell phone records to see who he had been speaking to in the days before his death. as yet, this remains an absolutely open question . the significance of what happened hire in terms of its broader connection to politics and public policy and also just the tragedy of this death. no suspects in custody, and no word on a motive. but
