DENVER (CBS4) – El Paso County security officials say a Colorado judge received threats related to the 211 Crew, a prison gang that has been investigated in connection with the killing of the state corrections chief earlier this year.

The manager of security for El Paso County told CBS4 partner KKTV-TV on Monday that the threats were made against County Judge Jonathan L. Walker in early August.

So far it’s not clear how the threats might have been related to the 211 Crew.

Martinez says an investigation is underway.

Evan Ebel, a member of the 211 Crew, is the only suspect in the killing of corrections chief Tom Clements in March. Clements was shot when he answered his front door. Ebel had recently been released from prison and is also suspected of killing Nathan Leon, of Commerce City, a few days earlier.

Ebel died in a shootout in Texas days later.

The word of a threat against Walker was investigated but could not be corroborated, according to sources that spoke with CBS4.

The judge returned to the bench on Monday after taking two weeks of vacation.
