Deputies found the keys to the car trunk that became Isaiah Theis' tomb lying next to the 2-year-old's body, the family's pastor said Saturday.
The ring of keys to the Chevrolet Impala was one of several sets of car keys found with the boy, said Pastor Rick Van Gundy.
How the toddler got into the parked car — which had been left for repair with his father, Justin Theis — and remained missing for nearly 30 hours is still a puzzle to police and neighbors in Centuria, where searchers repeatedly came within feet of the trunk where Isaiah was trapped before he was discovered.
"When we were doing the searches, they were looking for the keys," Van Gundy said. "They couldn't find the keys anywhere … I remember Justin saying, 'They should be right here, they were laying on my desk. He must have taken all the keys.'
"And then later, after they had found Isaiah, the family had told me that the keys to that car, and other ones, were with him."
The extreme heat in the closed trunk killed Isaiah, according to a preliminary autopsy report released Friday. On hot days, experts said, temperatures inside a vehicle can quickly reach 150 degrees or higher.
The child was last seen playing with his 7-year-old brother Tuesday evening, but no one opened the car or trunk until its owner showed up late Wednesday night to collect his vehicle.
"Hindsight is 20/20," Van Gundy said Saturday. "I myself looked in the car with a flashlight. I looked under the car with a flashlight. … It's just that at the time, the car is locked, and it's in your head that it's secure. You don't even put two and two together."
