Nearly 18 months after a pair of Fairfield, Iowa teens bludgeoned a Spanish teacher to death with a baseball bat after a dispute over a bad grade ― a brutal tragedy that shook the southeast Iowa city and people across the state ― they pleaded guilty to first-degree murder Tuesday.

Willard Miller and Jeremy Goodale were both 16 when they were charged with the Nov. 3, 2021 slaying of Fairfield High School teacher Nohema Graber, whose body was discovered in a city park, hidden under a tarp, wheelbarrow and railroad ties.

The town of Fairfield is home to some 9,400 people and is about 100 miles southeast of Des Moines.

As details of the ambush and killing emerged, it left the community of 9,600 in deep shock and mourning over the loss of the well-regarded educator and leader in the town’s small but growing Latino community.

“We’re glad the defendants have taken responsibility for the crime they committed and look forward to making sure justice is done at sentencing,” Jefferson County Attorney Chauncey Moulding said following the hearings.

Prosecutors will recommend that Miller, now 17, receive life in prison with eligibility for parole after 30 years, and that Goodale, now 18, be eligible for parole after 25 years.

Jeremy Goodale pleads guilty in the 2021 murder of Fairfield Spanish teacher Nohema Graber at the Jefferson County Courthouse in Fairfield, Tuesday, April 18, 2023.

Prosecutors said the teens ambushed Graber when she went for her daily afternoon walk, after Miller met with her to discuss his grade. Witnesses saw her van leaving the park less than an hour later with two males in the front seat; it was later found abandoned. Goodale and Miller were initially detained after a witness provided police with photos of a Snapchat conversation in which Goodale allegedly implicated himself and Miller in the killing.

Who was Nohema Graber?

Nohema Graber

Graber, whose family was in the courtroom for Tuesday’s plea, was days short of her 67th birthday when she was killed. She was born in Mexico and after high school worked as a flight attendant and later as a pilot with the now-defunct Mexicana de Aviación airline.

She moved to Fairfield, her then-husband Paul’s hometown, in the 1990s and earned an English degree from Iowa Wesleyan University in 2006. She taught Spanish at Ottumwa High School until 2012, then took the same assignment at Fairfield High School, serving there until her death.

Graber had three adult children, and in addition to them and her ex-husband was survived by several siblings and many nephews and nieces. In the days after her death, her family recalled her as an “absolute angel” and Fairfield schools Superintendent Lauri Noll said Graber “touched the lives of many students, parents and staff” in her nine years at Fairfield High.

What was the motive?

Willard Miller pleads guilty in the 2021 murder of Fairfield Spanish teacher Nohema Graber at the Jefferson County Courthouse in Fairfield, Tuesday, April 18, 2023.

Although prosecutors alleged in court filings that Graber had been beaten to death with a baseball bat and her body was hidden in Fairfield’s Chautauqua Park, it was not until almost a year after her death that they disclosed the alleged motive: Miller was upset about his grade in her class and had been seen arguing with her about it.
