CHARLESTON, W.Va. -- A Charleston woman who admitted to stabbing her boyfriend, indirectly causing his death, will spend up to a year in jail.Stacey McCormick, 20, who pleaded guilty last month to involuntary manslaughter charges linked to the death of her boyfriend, David Snyder, was sentenced Monday to a year in South Central Regional Jail."I just want to get home and mend the broken hearts," McCormick said Monday.In August, police arrested McCormick on charges of malicious wounding after Snyder said she stabbed him, leaving an inch-and-a-half-long gash in his chest.Snyder spent about three days at CAMC General Hospital before voluntarily checking out. He did not have medical insurance, his family members have said.Snyder died hours after he checked out. Medical examiners found that he bled internally when doctors removed a chest tube.McCormick was originally charged with murder. Prosecutors said they reduced the charges to involuntary manslaughter because they could not prove that the stabbing directly caused Snyder's death. He would have survived if the chest tube had not been removed, prosecutors said.Prosecutors also said that the only other person who was inside the house at the time of the stabbing was McCormick's brother.Snyder's mother, Delores Snyder, said Monday that she did not agree with the plea. She pointed out that McCormick has a history of charges related to domestic violence.McCormick was arrested and charged with malicious wounding and battery against David Snyder in 2007. Snyder also filed an emergency domestic-violence petition in October 2011 against McCormick, court records show."I just hope next time the person won't end up like my son did," Delores Snyder said.Reach Zac Taylor at firstname.lastname@example.org or 304-348-5189.
