SAN DIEGO -
According to information obtained by Team 10, years before he was hired by the Border Patrol, there were questions about whether agent Justin Tackett was fit to carry a badge or a gun.
Team 10 learned Tackett was previously a deputy with the Imperial County Sheriff's Department -- a job he quit days before he was going to be fired.
Team 10 found the termination letter from 2002, and it said Tackett was to be fired for "unprofessional conduct," "dishonesty," "refusal to obey reasonable regulations" and "insubordination."
The letter also said, "A deputy who cannot be trusted to tell the truth is a person who cannot be trusted with a badge or a gun."
Then-Imperial County Sheriff's Department Chief Sharon Housouer wrote Tackett repeatedly placed himself above "the department … and its mission …" "supervisors and their orders" and "fellow peace officers and ethical obligations"
The termination letter reminded Tackett, "you are not a law unto yourself but no more than an appointed deputy charged with enforcing the laws of the State of California and the County of Imperial."
Attorney Gene Iredale, who is representing the family of shooting victim Valeria "Munique" Tachiquin Alvarado, has started the process to file a lawsuit against the Border Patrol.
"Why would he be hired in the first place?" Iredale said. "With no change in his law enforcement training and no apparent change in his character a federal agency, the Border Patrol hires this man and trusts him with a gun and a badge."
When reached by phone Wednesday, Tackett said he had no comment for this story.
The Border Patrol did not return Team 10's calls for comment.
