The California Highway Patrol incident reports are maddeningly short on details, providing just a tantalizing hint of information. Take this report last night in Orange County, for example. I’ve translated some of the abbreviations and codes to English language and put the dispatches in chronological order.
The dispatch says “Santa Ana” but Weir Canyon Rd and the Riverside Freeway are actually in Anaheim (I think). “Santa Ana” is the local highway patrol office. “Station 17″ is presumably the local fire department.
