Did Patricia Terry Get Neglected by a Renal Center, a Nursing Home or an Ambulance Service? ~by Legal Pub

Back in October, 71 year-old Patricia Terry was allegedly abandoned at a dialysis facility. She died a few days later.  Terry's estate is suing the DaVita Renal center in Joliet, an ambulance company and a nursing home, Alden Estates of Shorewood.. Terry's family claims in a lawsuit that Patricia Terry was left alone in the waiting room of a dialysis facility due to negligence. Her dialysis treatment on Halloween had ended just after 7 p.m.. Patricia allegedly sat in the lobby in a wheelchair waiting for an ambulance to pick her up. The staff allegedly left the building at 8:45 and locked up. Terry's daughters called police who apparently were not able to get inside the center until around midnight.   that police were able to get inside. Terry was disoriented. She later died. On Wednesday the family filed a lawsuit against all three defendants.  

Was an ambulance ever called to transport Terry back to the hospital?  If not, who dropped the ball?  If so, why did the staff leave before Terry was safely in the care of the ambulance company?  Lots of questions with very few answers.
