Prosecutors are pursuing witness intimidation charges against a man accused of telling the mother of a Colorado Springs slaying victim: "You're next."
The chilling words were allegedly delivered by Angelo Joe Vigil, the cousin of a fugitive being sought in the Aug. 10 slayings of Camille Root and Daniel Castaneda, who were gunned down in an ambush on the city's east side.
Vigil, 33, was charged last month and is due to return to court Thursday, court records show. He is being held on $50,000 bond at the El Paso County jail.
According to an arrest affidavit, Vigil threatened Root's mother, Phyllis Cordova, during a Sept. 22. phone call in which he told her "they were not going to win" -- an apparent reference to the hunt for relative Gary Lee Vigil, who is charged in an arrest warrant with carrying out the killings.
When Cordova told him she didn't want to talk, he replied, "You're next," implying she too would be killed, police say.
Angelo Vigil is only the latest of the fugitive's relatives to be drawn into the case.
A sister, Regina Vigil, is accused of smuggling Gary Glen Vigil into Mexico days after the killings. The married mother of two was arrested in Texas and later extradited to Colorado, where she is awaiting trial on charges of accessory to murder.
Gary Glen Vigil is Root's ex-boyfriend, prosecutors have said in court, without identifying a specific motive in the killings.
Authorities say he lay in wait outside Nancy's Lion's Den at Platte Avenue and North Circle Drive and shot both victims in the head as they emerged - opening fire in view of at least one witness.
People familiar with the slain couple say Camille Root was several months pregnant.
Angelo Vigil was previously acquainted with the woman he threatened.
According to his arrest warrant, he is dating the sister of the slain woman.
