A teen suspected of carrying out an armed robbery that went sideways when a Louisiana shop manager open fire on him and his 16-year-old accomplice has been identified as an illegal alien who crossed the southern border last year as an ‘unaccompanied minor.’ Teony Umanzor-Juarez, 18, was arrested last week following the deadly incident, which unfolded just before 8 p.m. on Tuesday night in New Orleans. Two young males wearing masks entered Sam’s Meat Market and pointed guns at employees, surveillance footage shows.
