July 18, 2011 | 10:31 am
A Chino Hills woman who was trying to hang a bird feeder from her second-story patio lost her balance and fell to her death early Monday morning, authorities said.
The woman, who was not identified, died after an unsuccessful attempt by a Chino Valley Fire rescue crew to resuscitate her. The accident occurred at the Rolling Ridge apartment complex in the 13400 block of Peyton Drive.
According to a report by the San Bernardino County Sheriffs Department, the woman was trying to hang the feeder from a wood beam directly above her patio ledge around 3:45 a.m. She fell two stories down, landing on a concrete floor near the base of a staircase.
