The initial day of the legal proceedings marked the first time Erika, 37, came face to face with the man accused of using a rifle to kill her 31-year-old husband. Robinson, 23, wore a gray suit and shackles as prosecutors presented evidence about Charlie's murder on the campus of Utah Valley University. Erika, who is now a single mom of a 2-year-old son and a daughter who turns 4 in August, held hands with her mother-in-law, Kathryn, in the courtroom. However, Erika exited just before prosecutors played three videos showing the horrifying moment a bullet tore through Charlie's neck during a stop on his American Comeback tour at the school in Orem.
