It’s hard to accept that our son was shot and murdered with a gun that was bought in the U.S. We have not had any contact from the Border Patrol or any other agents since returning home on the 22nd of [January]. Our calls are not returned. I truly feel that our son’s death is a cover-up and they hope that we will go away. That will not happen. We want to know who allowed the sale of that gun that murdered our son. Any help will [be] appreciated. We are the victims of this case and we want some answers.
