A second body was discovered outside of a vehicle on Wednesday, as authorities attempted to recover vehicles that washed away due to the flooding in Sacramento County over the New Year's weekend, California Highway Patrol (CHP) told ABC News.
Officials discovered the woman's body around 10 a.m. in a field about one mile east of State Route 99, CHP said.
Authorities could not confirm if the body was connected to the vehicles they were towing until they could positively identify the person.
