Sullivan declined to comment Friday.
When Snyder was admitted to the hospital, doctors installed a tube on one side of his chest, according to Holstein. The tube was removed three days later, when Snyder was released.
Holstein said the state could show only a "causal relationship" between the stab wound and Snyder's death. Based on the autopsy report, which cited internal bleeding as the cause of death, they could not prove that McCormick intended to kill him.
Snyder's mother, Delores, said the family does not agree with the plea.
"If she hadn't stabbed him, he wouldn't be in the hospital," Delores Snyder said. "I'm just not happy with the situation at all."
Snyder said her son did not voluntarily leave the hospital the day that he died. He was discharged and sent home in a wheelchair and family was not there to pick him up, she said. He did not have medical insurance, his mother said.
McCormick faces up to a year in prison when she is sentenced March 1.
