A son suspected of killing his own father died in the hospital after mysteriously falling ill.
State police said 43-year-old Timothy Fitzsimmons allegedly killed his father Dennis Fitzsimmons, 74, on Tuesday at their home in Southbury.
Troopers said they were originally called to Jacob Road around 10 p.m. for a reported medical emergency.
When they arrived, they found Dennis Fitzsimmons lying on the floor of a home. He was pronounced dead at the scene.
A neighbor told Eyewitness News she tried to save the life of Dennis Fitzsimmons, all while trying to restrain the suspected killer in the process.
She said Timothy Fitzsimmons would not surrender without a fight.
"Then he kept flailing all over the place, hitting the body and that's when I knew there was more going on with him, so I wanted to restrain him from hitting the body, so I grabbed him by the neck and the arm, trying to put him on the floor," the neighbor, who didn't want to be identified, said.
No other victims were found in the home, but now a woman is left without a husband and a son.
Through the course of their investigation, troopers said they identified Timothy Fitzsimmons as the suspect. However, he suddenly became sick and unconscious.
Timothy Fitzsimmons was taken to Waterbury Hospital where he died around 11:30 p.m.
The neighbor said Dennis and his wife were both retired and former owners of Misfits in Southbury.
She said their attention in their retirement years turned to their miniature farm that they kept.
Police are investigating both deaths.
The Office of the Chief Medical Examiner is helping to determine the causes of death for both the victim and the suspect.
