The family of a Tri-Cities man who died after being found bloody and unconscious on the floor of an Eastern State Hospital restroom in 2013 is suing. Misael Rodriguez, 43, was involuntarily committed for observation purposes in mid-August of that year and suffered the fatal injuries 11 days later in what his family members allege was an assault by another patient, according to a lawsuit filed in Spokane County Superior Court last week on behalf of the victim’s children. Rodriguez died Nov. 13, 2013, without regaining consciousness.
