Here is the original story and event.Mountain Lion Attacks Child on Hiking Trail Near Cupertino Winery.
When I arrived at the location the whole area was blocked off, and their are search dogs in the area, so the MidPeninsula Regional Open Space Project, Fish and Wildlife, or Wildlife Management shut it down.
Reason is: the dog handlers/slash trappers, don’t want the scents confusing the search dogs. Technically it is believed that Mountain Lions, will stay near the area where the alleged attack occurred for several days. A Fish and Wildlife employee informed me that the cats in the area are already confusing the search dogs by criss-crossing the area repeatedly.
There are always signs posted informing hikers of the possibility of Mountain Lion encounters. In those areas, parents or guardians or chaperones must never let a child follow behind them. Children must always be in front of the parents or guardians.
Update: California Fish and Wildlife shot and killed the Mountain Lion on September 10 2014.
