A Monday argument over the cable television show The Walking Dead ended with a Long Island man firing a bullet into the back of his girlfriend because she would not take the possibility of a real zombie attack seriously.

In a press conference on Tuesday, Nassau County police Detective Lt. Raymond Cote said that 26-year-old Jared Gurman had shot his girlfriend, Jessica Gelderman, with a .22-caliber rifle resulting in a pierced lung, shattered rib and pierced diaphragm, according to WNBC.

"He feels strongly about the possibility that some military mishap could occur causing some tragic consequence," Cote explained.

But Gurman's girlfriend refused to believe that it was realistic to worry about zombie attacks like those depicted on the popular AMC show.

"She felt that it was ridiculous," Cote said.

Apparently tired of arguing, Gelderman drove Gurman back to his home and then she returned to her own own home. That's when the dispute escalated over text messages and she drove back to Gurman's home because she worried that he had become unstable.

"She tried to diffuse the situation and calm him down," Cote told reporters. "She was walking up the stairs to the apartment when Mr. Gurman raised the rifle, pointed it at her and fired one round into her back."

The woman begged Gurman to take her to the hospital. She was in stable condition on Tuesday but the bullet remained in her body. The suspect reportedly confessed to police after first telling them that the shooting had been an accident.

Police described Gurman, who was charged with attempted murder, as "passionate" about guns. At least three firearms were seized from his home.
