A Florida man is accused of murdering his parents and then traveling to another state where he threatened to kill other people.

Nicholas Steven Kirchner, aged 37, is charged with two counts of first-degree murder for allegedly killing his parents in Largo, as reported by the Pinellas County Sheriff’s Office in a press release.

The investigation commenced shortly after 12:30 p.m. on Friday during a welfare check at a Saunders Avenue home for an employee who failed to appear at work. Officers discovered the bodies of 53-year-old Elizabeth Lee Kirchner and 64-year-old Steven Eric Kirchner in the living room, both victims of gunshot wounds.

Roughly three hours later and some 460 miles away, deputies with the Taliaferro County Sheriff’s Office in Georgia received a 911 call from a motorist about a suspicious man in the shoulder of the highway. He was wearing all white and a red baseball hat and kneeling with one hand raised, the agency said in a press release.
