Search warrant documents unsealed this week show that two 16-year-old boys accused of killing an Iowa Spanish teacher last fall used a baseball bat to beat her to death.

The same documents say that one of the teens posted details of the crime on Snapchat, revealing how the boys followed her, beat her, and hid her body after her death, according to the Des Moines Register.

A hearing is scheduled for Thursday to determine whether Jeremy Goodale will be tried in the juvenile court system for the brutal death of 66-year-old Nohema Graber, who taught at Fairfield High School. A hearing for the other teen, Willard Miller, is on hold while the state Supreme Court considers a pair of appeals made by his attorneys.

As CrimeOnline previously reported, prosecutors said that Goodale and Miller stalked Graber before her death. They tracked Graber’s schedule and analyzed the times she took her daily walk, according to Jefferson County Attorney Chauncy Moulding.

Graber was found dead on November 3 in Chautauqua Park in Fairfield, buried beneath a tarp, a wheelbarrow, and railroad ties, the Register said.

According to the documents released this week, police viewed surveillance video that showed her car leaving the school where she taught and driving into the park at about 4 p.m. on November 2. Nearly 45 minutes later, her car left the park followed by a pickup truck.

About midnight, a witness reported seeing someone pushing a wheelbarrow toward the park. Another warrant said that Miller told police he provided a wheelbarrow from his home.

The documents also say that a friend of Goodale’s showed police the boy’s Snapchat messages, which indicated both boys “were involved in the planning, execution, and disposal of evidence.” The messages revealed where Graber’s body was buried and where her car was parked.
