An Illinois man fatally shot his partner before killing himself because he believed that they had the coronavirus, the Will County Sheriff’s Office said.

BuzzFeed News reports that a wellness check was conducted at the couple's home at around 8 p.m. on Thursday after the parents of Patrick Jesernik, 54, contacted authorities since they had not heard from him. The bodies of Jesernik, and Cheryl Schriefer, 59, were found in separate rooms "with obvious signs of trauma to their heads."
