Bicyclist vs animal

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.

Location: NORTHBOUND WEIR CANYON RD ON RAMP TO WEST BOUND HWY 91, Santa Ana
2/4/2010 9:28:47 PM

-- 9:28PM 2 BICYCLISTS ON THE ONRAMP
-- 9:28PM IT APPEARS THEY HIT AN ANIMAL
-- 9:28PM POSSIBLY A DOG
-- 9:41PM ROLL STATION 17, INJURED RACCOON
-- 9:43PM STATION 17 ARRIVED, ANIMAL CONTROL EN ROUTE

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.
