Here is a quote from the article:
"Jean Sepulveda, representative for the sheriff’s office, said an alert through the pilot’s equipment shows that he ejected himself from the aircraft before it crashed. His condition is unknown.
“They have not been able to clear enough brush so that a vehicle can reach the crash,” Sepulveda told the Daily News about 1:40 p.m. “He has not been located as of yet.”
