(DENVER) -- A manhunt was launched in Colorado on Wednesday 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 News 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, and according to KMGH they do not have a description of the shooter.
"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.
Clements is survived by his wife, Lisa Clements, and his two daughters. Hickenlooper on Wednesday ordered flags be lowered to half-staff at all public buildings statewide in memory of Clements.
