Suspect in Colorado prison chief killing had bomb-making materials in car, police say

Investigators found bomb-making materials, a mask, duct tape and even surveillance cameras in the car of the now-dead suspect in the killings of Colorado prisons chief Tom Clements and pizza delivery driver Nathan Leon.

The description of the found items come from a document – an evidence recovery log – that details what was recovered from Evan Spencer Ebel’s black 1991 Cadillac Deville when officers went to investigate.

The document was released by the Wise County Clerk's office on Tuesday and obtained by NBC affiliate KUSA.

Ebel, 28, was killed last Thursday in a gun battle with police after a high-speed chase in Decatur, Texas.

He is suspected of shooting Clements, executive director of the Colorado Department of Corrections, as he opened the door to his home near Denver a week ago.

Police also believe Ebel — a paroled convict who joined a white supremacist group while in prison — shot and killed Leon on March 17 in order to use his pizza delivery uniform as disguise to approach Clement’s home without suspicion.

Found in the trunk of the car and stuffed inside a black backpack were maps, bomb-making instructions, handwritten directions, letters to "Nate," a Colorado ID card, a Visa debit card, photographs and a plastic bag containing sunglasses and a mask. 

It was unclear if the letters were related to the slain pizza delivery man. "We don't know who Nate is," Wise County Sheriff David Walker told the Denver Post.

A cooler was also found in the trunk of the car. It contained tan pants with “apparent blood” and a tan jacket, according to the document. Other items included zip ties, a Domino’s “heatwave” pizza-delivery bag, a Domino’s pizza box, a Domino’s shirt, a Domino’s visor, and a digital-voice recorder.

Many of the items recovered by Texas investigators were sent to the El Paso County Sheriff's Office and the Denver Police Department, according to the document.

Ebel’s mother, Jody Mangue, wrote that her son “drifted into a dark period” after the death of his 16-year-old sister in a car crash in 2004.
