Three family members who were killed during what was described as a possibly “random” triple murder-suicide attack carried out by an unrelated person at an Iowa state park last month were shot, stabbed and/or strangled, according to autopsy results released Thursday.
42-year-old Tyler Schmidt died from a gunshot wound and “multiple sharp force injuries,” while his wife, 42-year-old Sarah Schmidt, died from multiple sharp force injuries, the Iowa Department of Public Safety said in a news release. Their 6-year-old daughter, Lula Schmidt, died from a gunshot wound and strangulation, officials said.
The Schmidts’ bodies were discovered on July 22 inside a tent at the Maquoketa Caves State Park Campground, which is located approximately 180 miles east of Des Moines. Their 9-year-old son, who was with his family on the camping trip, survived the attack without physical injuries, but investigators have not said whether he was in the tent when the attack happened.
The department confirmed Thursday that the killer was 23-year-old Anthony Sherwin, of LaVista, Nebraska, who died from a self-inflicted gunshot wound after the attack on the family early on the morning of July 22 in their tent at the Maquoketa Caves State Park campground. Sherwin was at the park camping with his parents at the time of the attack, according to police and Sherwin’s mother.
Investigators said all evidence collected substantiates that Sherwin acted alone, but police have not indicated a motive in the killings. The release said no further information would be released Thursday.
Mitch Mortvedt, assistant director of the Department of Public Safety’s division of criminal investigation, said last month that the initial investigation had “not revealed any early interaction between the Schmidt family and him.”
“We don’t know what led up to this, what precipitated it,” he reportedly said.
Adam Morehouse, Sarah Schmidt’s brother, told the news outlet the family had no connection to Sherwin and he believed it was a “completely random act.”
Police who swarmed the park in the wake of the shooting found Sherwin’s body outside the campground but within a wooded area of the park.
Sherwin’s mother, Cecilia Sherwin, said in the days after the shooting that she and her husband were devastated by attack on the Schmidts and by the loss of their son, whom she described as kind, sensitive, an exceptional student and an aspiring businessman.
