Perhaps the most famous was Anthony Elgindy, who made national news when his Olivenhain mansion was raided by the FBI. Elgindy had been a penny-stock operator in the mode of Wolf of Wall Street and Boiler Room, then turned FBI informant. What got him in trouble in 2002 was his relationship with crooked FBI agents who sold him information about pending FBI investigations into public companies. Elgindy then profited by shorting the stocks of those companies.
The lavish mansion raided in 2002 was on Calle Tres Vistas in Olivenhain. Public records also show Elgindy having lived on Rancho Encinitas Drive, at the opposite end of the loop from the Olivenhain drug house. Elgindy was believed to be living elsewhere in the San Diego area more recently.
Now Don Bauder in the San Diego Reader tells us:
Elgindy's son, Adam Elgindy, says on his Facebook page, "My dad, Anthony Elgindy, passed away yesterday. He was under so much stress and panic and he took his own life." Several of Adam Elgindy's friends sent him condolences such as "I'm sorry man, "if you need anything at all hit me up man," and "I'm praying god watches over you."Our condolences to the Elgindy family.
