Maquoketa Caves State Park camper heard a scream and a loud noise near site of triple homicide

MAQUOKETA — Felicia Coe awoke with optimism.

Coe, 35, checked her phone in her family’s pop-up camper at Maquoketa Caves State Park around 6:15 a.m. Friday. Her weather app told her that previous forecasts of all-day rain were overblown. She, her boyfriend and her 11-year-old and 16-year-old sons planned to hike through the park and explore the Rainy Day Cave, the Ice Cave and the Barbell.

She made coffee. Her 11-year-old pulled out a book. Her boyfriend stirred in his sleep. Her 16-year-old left for a morning run.

They heard a scream. Then they heard a second sound.

Her boyfriend thought he heard a firework. Coe told him no one would light an explosive so early in the morning. She believed someone slammed something — maybe a car door, maybe a trash can lid.

Later, they would learn the police account.

Law enforcement said Tyler Schmidt, 42, Sarah Schmidt, 42, and Lula Schmidt, 6, of Cedar Falls, died Friday morning, their bodies found in a tent about 100 yards from Coe’s camper. Cedar Falls Mayor Rob Green would later say in a Facebook post that another member of the family — 9-year-old Arlo — survived. State law enforcement did not say whether Arlo Schmidt was with his family at the time of the attack.

After a search of the park, investigators discovered the body of Anthony Orlando Sherwin, 23. They say he died from a self-inflicted gunshot. Though they didn’t know a connection or motive as of Friday, investigators said they believe he killed the Schmidts.

The shooting unsettled many connected to the park, from locals to visitors like Coe. A day later, several told the Des Moines Register that such an attack doesn’t fit anywhere — but especially not here.

Maquoketa Caves is one of eastern Iowa’s great gems, they say, a rare spot that proves Iowa isn’t all corn, soybeans and silos. Visitors come to hike, to explore caverns, to forget their jobs. They say they feel peace here.

Bob Sheets, whose kitchen overlooks the wooded valley and Raccoon Creek south of Maquoketa Caves, said he’s never heard of a violent crime at the park in his 45 years here.
