One Year After Death Of Prisons Director, Questions Remain

On March 19, 2013, the Colorado prison director was gunned down in his own home.

One year later, authorities say they aren't ready to release many more details about the investigation that's taken place since then.

The El Paso County Sheriff's Office says releasing those details could jeopardize the investigation.

No one has been formally arrested for the murder of Tom Clements, but Colorado parolee Evan Ebel has long been named the suspect. Ebel, however, was killed in a shootout in Texas within days of Clements' death. Answers to some questions that could help with the investigation may have died with him.

Concerns have been raised about a "hit list" that Ebel may have had, and has also raised questions as to whether or not he worked alone. The sheriff's office says anyone else they know of who may be in danger was notified right away and security measures were put in place.

The sheriff's office did confirm to 11 News that they are still trying to determine whether Ebel worked alone, and if he didn't, what role did others involved play in the murder.
