(ABC NEWS) -- A manhunt has been launched in Colorado after the head of the state's prison system was shot and killed in his home.
Tom Clements, 58, was shot to death around 8:30 p.m. Tuesday in Monument, Colo., ABC affiliate KMGH reported. Police said that a member of Clements' family called 911 to report that he had been shot.
Sheriff's Lt. Jeff Kramer said that Clements was shot as soon as he answered the door at his home.
Authorities have said that a gunman is on the loose, but according to KMGH they do not have a description of the shooter. Police were going house to house trying to find out what neighbors heard and saw, the AP reported.
"We did have some efforts from our K-9 unit to see if they could locate anything that might be helpful in this investigation. Those efforts have been met with negative results," Kramer said.
Clements, 58, was appointed head of Colorado's Department of Corrections in 2011 by Gov. John Hickenlooper. He had served 31 years in the Missouri Department of Corrections, according to his Department of Corrections biography.
The AP reported that in a statement released early today and sent to department employees, Hickenlooper said he was in disbelief over the killing.
"As your executive director, he helped change and improve (the department) in two years more than most people could do in eight years. He was unfailingly kind and thoughtful, and sought the 'good' in any situation. I am so sad. I have never worked with a better person than Tom, and I can't imagine our team without him," he said.
Clements is survived by his wife, Lisa Clements, and his two daughters. Hickenlooper today ordered flags be lowered to half-staff all public buildings statewide in memory of Clements.
