Spanish Ex-Nursing Home Worker Killed 11 Residents A jury has convicted a former Spanish nursing home worker of killing 11 residents over a one-year period by forcing them to drink toxic liquids like bleach. Joan Vila confessed during his trial but claimed he killed to ease the pain and suffering of his victims. Following his conviction Tuesday, prosecutors who presented evidence they argued showed that he did not kill out of mercy said they would seek a 194-year sentence. Vila's defense lawyers say he is mentally ill and are asking a judge to impose 20 years of probation. The killings happened in 2009 and 2010 at the nursing home in the small northeastern city of Olot near the border with France.
