Investigators with the Oshkosh Police Department have determined a patient who died at the Winnebago Mental Health Institute fell on purpose.  That’s one of the reasons prosecutors have decided not to charge anyone in the death.  The man’s name hasn’t been released.  Wisconsin regulators became involved when it was discovered that the patient wasn’t transferred to a hospital for 14 hours after suffering a head injury.  He required surgery for bleeding on the brain, then died a few weeks later.
