A Florida landlord gunned down a family of four with young kids and burned their remains in the fire pit of the home they shared, US police said Tuesday.

Rory Atwood, 25, allegedly admitted to slaughtering the “transient” family — which included 5- and 6-year-old children — after getting into a dispute with the parents, who he was friends with since high school.

“If there wasn’t evil in this world, we wouldn’t have to pray as much. And when I talk about this story today, you’re going to hear about evil,” Pasco Sheriff Chris Nocco told reporters.

Atwood initially denied having any knowledge of the whereabouts of the Zilliot family, which included Rain Mancini, 26; Phillip Zilliot II, 25; and their young kids Karma and Phillip III, 6 and 5, respectively, Nocco said.

The family, who was staying at Atwood’s Hudson home, were reported missing Thursday by Mancini’s mother after the mom-of-two failed to keep up their daily communications, reports New York Post.
