MANCHESTER, Iowa (AP) — Autopsy results show a Manchester couple died of gunshot wounds, authorities said Wednesday.
Their bodies were found in their home on Mother's Day, and their grandson, 17-year-old Isaiah Sweet, faces two counts of first-degree murder. He is being charged as an adult.
An autopsy showed that Richard Sweet, 55, and his 62-year-old wife, Janet Sweet, were fatally shot, Delaware County Attorney John Bernau said. He declined to provide additional details, citing the ongoing investigation.
The bodies were found Sunday.
According to a criminal complaint, Isaiah Sweet called a friend Friday evening and told her he “drugged his grandparents” and thought they were dead. He called the friend again Saturday morning and said he had killed his grandparents, the complaint said.
“The cause of death was a shooting,” Bernau said. “Not by poisoning.”
The teen was arrested Monday night in Cedar Rapids after a short chase.
Bernau said that even though Sweet is charged as an adult, “he has to be housed by sight and sound restrictions as a juvenile.”
Sweet's preliminary hearing in Delaware County District Court is May 25.
