It's a horror story that every witness fears in a crime case: criminals find out about your identity and murder you for doing the right thing and helping the police solve a crime.

But for the family of David Henderson, 48, this horror story is compounded by who gave information to his killers in Denver. District Court officials mistakenly released secret court documents identifying Henderson's appeal and other important clues to a robbery team of mother and son he had reported to police officers. This is from an affidavit released in Arapahoe County, Colorado on Thursday. On December 1

2, 2016, Henderson, a car mechanic, was shot and killed ten times in front of the house in Denver where he lived with his mother. The prosecutors say the motive for the murder was Henderson's collaboration with detectives when he described the details of a robbery of marijuana shops two months ago.

"This is the nightmare scenario," said George Brauchler, Arapahoe District District Attorney, closing a loophole to ensure that criminals do not get such documents back, Brauchler said.

The robbers who bring the documents to court have orchestrated the execution style, Terance Black (26) and his mother, Tina Black (51). Both were sentenced to life without parole on Thursday, but Henderson's family still feels that Pain of the legal error.

Henderson's sister said her family had difficulty recovering. She described her brother as a carefree man with a knack for car repair who feared retribution, but he still wanted to help, Karen Henderson said.

"He did not have adequate protection," she said. "It's just a shame that his life was used for the right thing."

The prosecutors praised Henderson's intentions.

"David Henderson is someone who must be praised for his courage and courage in order to go forward and do the right thing," Brauchler said before sentencing Thursday.

Henderson had contacted the police to Suspicious activity reported by Tina Black, who had ordered him to do her cars mechanically.

In August, police confiscated Henderson's information about the armed robbery in a suburban suburban marijuana business, and the prosecutors reported that Terance Black He learned from Henderson's cooperation with the police when he was in custody of the robberies that discovery documents that provided evidence of the robbery were mistakenly sent to someone in the investigation, who called Terance Black and told him the mechanic have spoken to the police, reported the post.

Terance Black is in the egg quoted the tacit declaration and says he got "the guy's court papers." the robbery.

Terance Black told a friend that he had read court documents pointing to Henderson as a witness and that he had "run his mouth … Terance Black said he had read half of it and Mr. Henderson's name" Anywhere, narrative "," according to a criminal affidavit. "

Terend Black told the acquaintance that if Henderson did not show up for the testimony," they would not have a case, "the affidavit said." They could not prosecute her because Mr. Black also said, "We have to kill him."

Both Terance and Tina Black were heard at some point that Henderson had said snooping and sniffing stings, "the affidavit said.

A Colorado Court of Justice spokesman said the cause for the publication of the erroneous files was resolved this summer after the Brauchler bureau had notified administrators.

Spokesman Rob McCallum said in several districts judges were automatically released to all parties involved in a case, including defendants and witnesses.

The officials estimated that 1,500 cases were affected. Officials stated that no other defendant case is known for being charged or threatened with witnesses based on erroneously released court records.

The updated system, which was introduced in August, requires judges to specifically select which parties to receive those court records, McCallum said.
