LATEST: Family members identify the victims as Susan Nash and two of her four children. More than 100 people were at a vigil on Monday.
Nash worked for more than a decade at Desert Pines High School, according to coworkers on the scene. They say she was a teacher's aide for special needs children.
"Just why...why did you have to shoot everybody?" said friend Trisha Rose.
Both of Nash's children were also parents. The family has created a GoFundMe account to assist with expenses after this stunning loss.
"It's too much evil in the world," said Rose.

The preliminary investigation indicates the two men, 26 and 31 years of age, and two women, 52 and 20 years of age, were in the parking lot when an argument ensued with an unknown subject. The suspect allegedly shot all four people before fleeing the scene. Investigators are still looking into the relationship between everyone but do not believe this is a random act of violence.
No arrests have been made.
A vigil was held Monday evening for the three killed.
