Despite the recent death of a sword-wielding man on the grounds of the Scientology Celebrity Center in Los Angeles, a church spokesman says an upcoming star-studded fund-raiser will proceed as planned.

“We’re already rolling with rehearsals,” spokesman Tommy Davis tells PEOPLE. “They’re going on this week and next.”

Kirstie Alley, Jenna Elfman, Anne Archer and Danny Masterson are some of the celebrities expected to participate in the annual event to be held Dec. 5 and 6 near the site of last Sunday’s fatal shooting by security guards.

The shooting occurred when the Mario Majorski, 48, reportedly emerged from his car, brandishing a samurai sword in each hand, then approached a trio of security guards. One guard opened fire with a semiautomatic handgun, killing the man. Surveillance tapes back up the guard’s version of the story that he shot in self-defense.

The victim reportedly had a strained history with the church. Los Angeles Police have thus far declined to file any charges in the case.

“This was an unfortunate incident, but we plan to carry on with our service to the community,” says Davis. Proceeds will benefit the Hollywood Police Activities League, a mentoring program for local youth.
