Concord , Calif -- The California Highway Patrol said 10 cows wandered into traffic after they escaped from a trailer on Highway 4, near the interchange with Interstate 680.
CHP officer Tom Maguire said five of the 10 cows died or had to be euthanized due to injuries sustained during collisions with passing vehicles, the Contra Costa (Calif.) Times reported Friday.
Highway patrol spokesman Sgt. Trent Cross said officers received reports of cows stampeding in traffic near Concord starting at 8:24 p.m. Thursday. He said the cows escaped from a trailer that had broken loose from its vehicle.
"I've never seen nothing like this. This is crazy," officer Tom Stewart said. "I'm not joking, they're everywhere."
