City officials are scrambling over the holiday weekend to try to figure out how to accommodate a public memorial service for Michael Jackson at a venue that can hold no more than 20,000 people.

The event has been set for 10 a.m. Tuesday at the downtown Staples Center, according to a statement from the Jackson family’s publicist. Eleven thousand tickets will be distributed, the statement said. The service is expected to draw tens of thousands of spectators wanting to pay their respects to the King of Pop, who died June 25. How city officials will handle the massive crowd remains to be settled.
