Police allege Velazquez-Nava steered his sport utility vehicle into the wrong lane of Pacific Coast Highway in Pacific Palisades early Wednesday, striking Clark’s sedan head-on. The filmmaker and his son, Ariel Hanrath-Clark, 22, died at the scene. Federal authorities have placed an immigration hold on a 24-year-old Mexican national arrested on suspicion of driving drunk and causing the crash that killed “A Christmas Story” director Bob Clark and his son, officials said Thursday. U.S. Immigration and Customs Enforcement put the hold Wednesday on Hector Velazquez-Nava, an illegal immigrant living in Los Angeles, said agency spokeswoman Virginia Kice. The action means Velazquez-Nava will be turned over to federal immigration officials and placed in deportation proceedings once his local case is completed. He was arrested for investigation of driving under the influence of alcohol and gross vehicular manslaughter, and was being held on $100,000 bail in a county jail. If he were to post bail, Velazquez-Nava would be taken into federal custody on the immigration hold, Kice said.
