A law enforcement official says the powerful sedative Diprivan was found in Michael Jackson's home.
Diprivan is an intravenous anesthetic drug widely used in operating rooms to induce unconsciousness. Also known as Propofol, it's very unusual to have in a private home.
The law enforcement official spoke on condition of anonymity because the person was not authorized to speak about the matter.
The Jackson family said in a statement that the event has been set for 10 a.m. Tuesday at the downtown Staples Center.
Los Angeles City Councilman Dennis Zin says the service could draw 100,000 fans. The center's capacity is about 20,000.
He says with the July Fourth holiday weekend "it's the worst time ... to work something out." He also says he's concerned about the cost of police overtime for the cash-strapped city.
