The Pennsylvania Office of Attorney General on Thursday charged a licensed practical nurse with involuntary manslaughter in the April 13 death of Herbert R. McMaster Sr. in the nursing home at Cathedral Village, in the Upper Roxborough section of Philadelphia. Christann S. Gainey, 30, was also charged with neglect of a care-dependent person and tampering with records for allegedly failing to provide appropriate care to McMaster, the father of former national security adviser H.R. McMaster Jr., after he fell in his room and hit his head, according to an eight-page criminal complaint.
