It would have been simple to find Clements' house. It took two clicks to get his street address through a publicly available Internet locator service Wednesday morning. The listing also included his previous address in Missouri.
McGovern said he tells his prosecutors to assume that any possible assailants can find their home addresses online and to check for areas they may be especially vulnerable such as neighboring alleys and poorly lit porches.
There is no central database of attacks on legal officials and senior law enforcement executives like Clements.
McGovern has documented 133 of them in the U.S. since 1950 by searching news accounts and court cases. The total includes 41 killings of judges, prosecutors and other justice and police officials. The assaults usually come with little warning, he said.
Steven K. Swensen, a former U.S. Marshal who runs a business consulting on security for court officials, said attacks on legal staff used to occur in courtrooms. As security has been expanded to protect those rooms, then courthouses, the attacks have spilled out further and further.
"Now we're having more violence off-site, in judges' houses, on their way to and from work," Swensen said.
Clements' survivors include two daughters and his wife, who is director of the state Office of Behavioral Health.
While Clements generally kept a low profile, his killing comes a week after he denied a request by a Saudi national to serve out the remainder of a Colorado prison sentence in Saudi Arabia.
Clements also recently requested chemicals to execute Nathan Dunlap, who was convicted of killing four people in a 1993 shooting rampage at a Chuck E. Cheese restaurant and is scheduled to become the second person executed in Colorado since the death penalty was reinstated by the U.S. Supreme Court in 1976.
Clements' father-in-law, Carroll Smith, told The Denver Post (http://bit.ly/YX6lLN) that Clements opposed the death penalty.
Earlier this week, Clements spoke to legislators about the need for more security staff in the department's food service areas, Department of Corrections spokeswoman Alison Morgan said. Last year, a kitchen worker at a state prison was killed and another was injured in an assault involving an inmate.
Clements is at least the second state prisons chief killed in office. Michael Francke, director of the Oregon corrections department, was stabbed to death outside his office in 1989 in what prosecutors described as a bungled car burglary. A former Oregon prison inmate was found guilty of aggravated murder in 1991 and sentenced to life in prison.
Hickenlooper ordered flags lowered to half-staff at public buildings until the day after Clements' funeral.
