DENVER - The white supremacist accused of killing Colorado's prisons chief may be connected to another high profile white supremacist who is currently serving a life sentence in prison.
Evan Ebel is accused of killing Tom Clements, the executive director of Colorado's Department of Corrections last week.
For years, Ebel had spent time locked up behind bars in the Sterling Correctional Facility for carjacking a man's vehicle and pistol whipping the driver. For other circumstances, he had been placed in solitary confinement.
In the same prison, under the same confinement, a man who many Coloradans had come to know for committing a despicable crime in 1997 was also locked up: Nathan Thill.
Thill is spending a life sentence without parole for the murder of an African immigrant name Oumar Dia.
At the time, Thill was a leader with a white supremacist group in Colorado. 9 Wants to Know has learned he's also connected to the same white supremacist group Evan Ebel was a part of.
A few days ago, now deep in to the investigation in to the murder of Tom Clements, the El Paso County Sheriff's Department asked the Colorado Department of Corrections to stop releasing information about Nathan Thill to any media outlet.
When 9NEWS asked whether Thill was part of the investigation, Sgt. Joe Roybal with the El Paso County Sheriff's Department said, "We are trying to identify any associates."
It's important to note that the sheriff's department is not naming Thill as a person of interest. But the fact they blocked his information directly after the investigation does raise some questions.
9NEWS asked Sgt. Roybal how many other inmates' information had been blocked since the investigation and he could not provide us with that number.
Both Thill and Ebel had been in solitary confinement, where each prisoner is separated and kept in a cell for 23 hours a day, only allowing them one hour to exercise.
