Pennsylvania. (AP) Pennsylvania's top prosecutor has opened criminal investigations into several nursing homes amid a coronavirus outbreak that has killed 2,600 residents of nursing homes and other facilities that care for older adults, more than two-thirds of the state's death toll, his office announced May 12. The attorney general's office did not say how many facilities it is investigating, or reveal their names or provide any other details about the specific allegations. In general, the attorney general's office has jurisdiction in manners of criminal neglect. Attorney General Josh Shapiro said in a written statement. "While we salute and appreciate nursing home staff on the front lines during this pandemic, we will not tolerate those who mistreat our seniors and break the law.'' He said "active criminal investigations" are underway. The virus has sickened about 12,000 residents of 540 nursing and personal care homes, accounting for about one-fifth of the state's confirmed infections, according to the Health Department. The National Guard has been deployed to more than a dozen homes with severe outbreaks. Shapiro's involvement comes as the administration of Gov. Tom Wolf rolls out a plan to begin universal coronavirus testing of every resident and employee of nursing homes and other facilities that provide care for older adults.
