SoCal man's body found in same San Diego hiking area where OC mom died after falling over waterfall

SAN DIEGO COUNTY, Calif. (KABC) -- A Rancho Cucamonga man has died in the same hiking area where a Ladera Ranch mom was killed when she fell over the edge of a waterfall and landed in the water below.

Richard Oliver, 28, went missing Friday at Three Sisters Falls in San Diego County.

His body was discovered in the center pool of the area.

Earlier this month, 48-year-old Sarah Crocker died at Three Sisters Falls when she slipped and fell while trying to help a teen.

Both went over the edge of the water and landed in the pool of water below. Crocker died from her injuries.

Cleveland National Forest officials are telling hikers they need to know and understand the trails before setting out on them.

"Take a look at what trail they want to go to, assess their own conditions and see if they can go out there if it's safe for them to do so," said Nathan Judy.
