The 48-year-old driver and his family, who are all deaf, had waited for several minutes at a downtown intersection Saturday as a large crowd taking part in the walk, including some in zombie makeup, went by at around 5:30 p.m., Officer David Stafford said. After waiting about 10 minutes, the motorist started honking his horn and inching forward into a crowd that included children and babies in strollers, Foley said in an email to U-T San Diego (http://bit.ly/1roHVIa ).
