Funeral arrangements for 2-year-old Isaiah Theis are planned for this week.

There will be a visitation Tuesday from 4 to 8 p.m. at the convention center at the Trollhaugen ski resort at 2232 100th Ave, Dresser, Wis. The event is open to the community.

On Wednesday, there will be a visitation starting at 10 a.m. at Alliance Church of the Valley at 1259 State Road 35 in St. Croix Falls. The funeral will be at 11 a.m. with a private burial for family members.

Isaiah was found last week in the trunk of a car that his father was repairing near his Centuria home after he went missing for nearly 30 hours. A preliminary autopsy report showed that the boy died from hyperthermia.

The family’s pastor says that it was likely that Isaiah climbed into the car trunk himself after grabbing the keys.

“Isaiah was an extremely bright little boy and extremely inquisitive,” said Rev. Rick Van Gundy.

He was obsessed with keys, trucks and cars, Van Gundy said.

“All it would have taken is one time of him watching his dad open the trunk,” Van Gundy said, explaining how the boy could imitate others.

A memorial fund for the Theis family has been created at
