Officers responding to a 911 call shortly after 6 p.m. found Ira Eugene Polonsky lying in a hallway at 1812 Capitol St. in central Vallejo, police said.
Polonsky was transported to Kaiser Hospital, where he was pronounced dead.
One of Polonsky's patients, who arrived at the scene Wednesday morning to offer her help to police, said she had seen Polonsky for an appointment about mid-day Tuesday, and she noticed nothing out of the ordinary. She told reporters that she couldn't imagine why anyone would want to kill Polonsky, who, she said, had a calming and uplifting effect on people.
Dr. Polonsky was a skilled and compassionate man, and our world will be poorer without him.
When further details become available, I will update this.
