An autopsy has determined the death of a Webster City man over the weekend was a homicide due to blunt force trauma.
The preliminary autopsy report for Steven Graesch, 61, of Webster City, was completed Tuesday at the State Medical Examiner's Office in Ankeny.
His son, Corbin J. Graesch, 27, has been charged with first-degree murder.
The body of Steven Graesch was found at the home he shared with his son at 1932 Des Moines St. early Monday morning.
The younger Graesch is being held in the Hamilton County Jail on $250,000 bond.
According to the criminal complaint filed against Corbin Graesch, he told investigators he got into a "physical altercation" with his father late Saturday night into early Sunday morning.
"During the altercation, Corbin hit his father multiple times with a blunt object as well as his fists, killing him," the complaint stated.
Neighbor Marsha Severson said Corbin Graesch "always seemed like a nice kid."
"We were outside playing all weekend," Severson said. "We didn't think there was anything going on."
She said she even saw Corbin Graesch leave the home Sunday afternoon.
Another neighbor, Jessica Thompson, said the father and son had lived in the home for about 12 years.
"It's just so sad," Thompson said. "We were all shocked by it."
Neighbors also stated that they had seen police officers at the home on different occasions.
Webster City Police Sgt. Ed Wardell confirmed that officers had responded to the Graesch home in the past.
"I have been to the home for previous altercations," he said. "They are usually family issues. The kid wants to borrow the car, and Dad won't let him. We have talked to the family before."
Though he said altercations had happened before, Wardell didn't know what caused the fight that led to Steven Graesch's death.
Corbin Graesch's preliminary hearing has been scheduled for June 19.
