The Fairfield, Iowa teacher who was allegedly murdered by two students gave an interview to a newspaper just a day before she died — and she talked about mortality. 

"We all know we are going to die," she told the outlet as she visited the town's library to admire a display commemorating the Day of the Dead, which is celebrated by people of Mexican heritage. 

"It’s our way of laughing at death," according to KCCI.

Preliminary evidence indicates that she suffered from "trauma to the head," according to court filings. Her body was located at Chautauqua Park.

Willard Noble Chaiden Miller and Jeremy Everett Goodale, both 16, were charged as adults in the killing.

Police received a tip that Goodale posted details about planning the killing and a possible motive on social media, according to court documents. Authorities have not yet released the motive. The court documents indicated police investigators found clothing that appeared to contain blood at the homes of the teens.

Graber was born in Xalapa, Mexico, the capital of the state of Veracruz, about 180 miles east of Mexico City. She moved to Fairfield, the hometown of her husband Paul Graber, in the 1990s. They divorced five years ago but remained close, he told The Des Moines Register.

Gov. Kim Reynolds ordered all flags in the state to fly at half-staff Tuesday to honor the teacher.

"My heart goes out to the family, friends, colleagues, and students that are dealing with this tragic murder of Nohema Graber," Reynolds said, according to KYouTV.com. "Ms. Graber touched countless children’s lives through her work as an educator across our state by sharing her passion of foreign language."

Assistant Jefferson County Attorney Patrick J. McAvan said Friday that many people are asking if this is a racially motivated crime. "We do not have any evidence at this point that suggests that," he said.
