That would stand in contrast with Robinson's family. They have yet to make a formal statement to the media, but authorities said it was Tyler's father, Matt Robinson, who convinced him to turn himself in. Tyler's grandmother, Debbie Robinson, 69, told the Daily Mail on Friday that the 48-year-old father is a Trump supporter. "My son, his dad, is a Republican for Trump, she told the outlet. "Most of my family members are Republican. I don't know any single one who's a Democrat."
