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.

"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.

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.
