Roberto Guadalupe Vasquez, a 27-year-old Hispanic man, was found suffering gunshot wounds near the front of a house at 1736 S.E. 8th Avenue in Amarillo, Texas, on December 21, 2015. He was taken to a hospital and later died of his injuries.

The investigation produced four arrests: two juvenile males, then ages 15 and 16, whose names were not released, and two adults, Melchor James Vences, 22, and Brendan Paul Givens, 20, who were serving unrelated jail terms when murder warrants were served. The Amarillo Police Department’s Special Crimes Unit continues to investigate and has said additional witnesses or information may exist.

No public resolution has been reported; the case remains open. If anyone knew Roberto, was in the neighborhood that night, or has information that could help, please contact the Amarillo Police Department.
