‘Duck Sauce Killer’s bid to protect neat wife

The accused “Duck Sauce Killer” hid eight guns in his estranged wife’s apartment, her lawyer said Tuesday — and everyone knows they were his because the closet was repulsively messy.

Glenn Hirsch — who allegedly gunned down Chinese-food delivery man Zhiwen Yan in Queens amid a dispute over duck sauce — wrote in a note before committing suicide Friday that his wife, Dorothy, had no idea he stashed the guns in her Briarwood apartment, in a closet stacked to the ceiling with trash bags, Ziploc bags and toilet paper, a new court filing indicates.

“Wrapped in tin foil and plastic, the firearms were stored in garbage bags and boxes consistent with his clustered method of storage and inconsistent with Dorothy’s neat manner,” lawyer Mark Bederow wrote in a letter to the Queens District Attorney’s Office.

“Not surprisingly, Glenn has admitted that he was the exclusive owner of the firearms and that he placed them in the closet he maintained at Dorothy’s apartment without her knowledge,’’ said Bederow, who is trying to get charges related to the guns against Dorothy dropped.

Glenn Hirsch, who was out on bail in the slaying, committed suicide Friday morning — before a court hearing that could have put him back behind bars awaiting trial.
