ALBUQUERQUE (AP) -- Classes will no longer be taught in a bloodstained portable building where police say an elementary school occupational therapist fought with her killer.
"The portable will be removed" from Montezuma Elementary School, Rigo Chavez, an Albuquerque Public Schools spokesman, said Tuesday.
Investigators on Tuesday were still trying to find the body of Carolyn Thurman Rustvold, 28, of Albuquerque, who was last seen Friday at the school.
"Detectives are just following up some leads," said Detective Jeff Arbogast of the Albuquerque Police Department.
Martin Saiz, 20, was arrested Saturday at his home in Los Lunas, south of Albuquerque.
He was being held Tuesday in the Bernalillo County Detention Center on charges of murder and tampering with evidence. His bond has been set at $800,000.

Investigators found pools of blood in Rustvold's portable classroom and in another classroom 50 yards away, police said.
Rustvold apparently struggled with her killer in her classroom, then her body was dragged to a kindergarten classroom, police have said.
Grief counselors were at the school Tuesday to help teachers, students and parents.
"The teachers have been told that it's OK to reach out to other staff if they need a hug and that they can show their emotions around students," Chavez said. "It's OK to cry."
Annette Duran escorted her son to the side of the school closest to his class Tuesday morning, then told him she would watch him go the rest of the way.
"I talked with him, and my parents talked with him about what happened," she said. "I don't think we said too much, but we did talk about what happened. He knows it's OK to feel sad for the family."
Arbogast said a crime "like this affects the entire community, police officers included."
"Sometimes officers become callous and have to get used to certain things that they see, but I don't think any officer gets used to a tragedy like this," he said.
