A driver arrested after the crash that killed "A Christmas Story" director Bob Clark and his son pleaded not guilty Friday to two counts of gross vehicular manslaughter while intoxicated.

Prosecutors say Hector Velazquez-Nava, 24, steered his sport-utility vehicle into the wrong lane of Pacific Coast Highway early Wednesday. Clark, 67 and his son, Ariel Hanrath-Clark, 22, died at the scene.

Velazquez-Nava had a blood-alcohol level of 0.24 percent, three times the legal limit, authorities said.

Velazquez-Nava was being held on $200,000 bail, although a federal immigration hold prevents him from posting bail. Immigration officials have said he is in the country illegally.

If convicted, he could face at least 10 years in state prison, prosecutors said.
