MONROE — A mobile home park is the fictional setting for an annual murder-mystery fundraising dinner at the Evergreen State Fairgrounds.

The dinner theater, dubbed “Trailer Park Tragedy,” is scheduled to begin Saturday at 6 p.m. and to last several hours.

Think of it as acting out an Agatha Christie novel, with some heavy Snohomish County flavor.

“The moment you walk through the door, you are part of the murder mystery because the characters are all over and mingling and doing their thing,” county parks director Tom Teigen said.

It’s the seventh year that fairgrounds and county parks staff have put on a dinner and a silent auction to benefit local food banks. To date, the dinners have raised more than $23,000 for the Sultan, Sky Valley, Maltby and Snohomish food banks.

This year’s adventure begins with an introduction to Big Hoss Beaver, the owner of the Starlight Trailer Park. He’ll invite guests to his annual appreciation picnic for the community. At some point, somebody gets killed and the guests have to figure out who dunnit.

The non-fiction menu for the night includes BBQ brisket, baked chicken, potato salad, baked beans, corn on the cob and rolls. Costumes are not required but prizes will be awarded for best costume.

Tickets are $25, available at the fairgrounds on 14405 179th Ave. SE, Monroe or at the county offices at Willis Tucker Park on 6705 Puget Park Drive, Snohomish. Ideally, people are asked to reserve a spot by Wednesday.

Sponsors include ACT Theater, Anthony’s Woodfire Grill, Emerald Downs, Experience Music Project, Outback Steakhouse, Seafair, Studio East Theater, Tulalip Casino and Wellbeing Massage.
