The family of a St. Helens-area mental health worker who was stabbed and killed by a client in May of 2012 is now suing the State of Oregon and a number of other agencies, claiming that they were negligent in allowing her killer out on the street. The Oregonian is reporting that the family of Jennifer Warren is suing Columbia County Corrections, the Oregon State Hospital, Greater Oregon Behavioral Health Incorporated, the Department of Administrative Services, Wasco County Corrections and the Oregon Department of Justice, asking for $2.5 million in a wrongful death suit. Warren was working as a health support worker for Columbia Community Mental Health when she was sent to the home of Brent Redd of St. Helens. She was stabbed to death as she tried to deliver medications for mental illness to Redd. In the suit, Warren’s family contends that the agencies involved failed to warn her that Redd was a dangerous man, and they also failed to properly evaluate Redd’s mental condition, which made him unsuitable to live in the general community. They also say that Warren should not have been alone, saying that as a single woman, she was at an increased risk of attack. Redd had been committed to the State Hospital in 2007, after trying to strangle his mother. He was released in 2010 by the Psychiatric Security Review Board, and then the Wasco County Circuit Court placed him in St. Helens.
