University of Idaho student Xana Kernodle received a DoorDash delivery less than 20 minutes before she was stabbed to death inside her home, according to an arrest affidavit released Thursday.

The 20-year-old marketing major’s final meal — likely from Jack in the Box, as The Post’s pictures taken inside the house show — was dropped off by a driver at the house on King Road in Moscow at 4 a.m., according to the probable cause affidavit.

Kernodle was active on her phone at 4:12 a.m. but had been slaughtered alongside her boyfriend Ethan Chapin, 20, in her bedroom by 4:25, investigators said in the report.
