The accused killer of four people in a Washington, DC, mansion hates pizza — and he claims that proves cops have the wrong man.

Daron Wint was caught by DNA on a pizza crust left inside the home of Savvas Savopoulos, who was stabbed to death along with his wife, 10-year-old son and housekeeper before the mansion was torched, ­authorities say.

Days later, cops arrested Wint, 34.

But Robin Ficker, a lawyer who represented the suspect in the past, said Saturday that Wint couldn’t have done it because of his distaste for pizza.

“He doesn’t eat pizza,” Ficker told ABC News. “He wouldn’t order pizza.”

Cops have wrongly stopped looking for the real killers, the lawyer complained, adding law enforcement has “blinders on” about Wint.

“They believe, perhaps honestly, that they have the man,” he said. “. . . [T]hey’ve closed their eyes.”
