The district arranged additional counselors and a visible police presence as schools reopened. Bend police spokesperson Sheila Miller said an officer would be at every school at the start and end of each day this week.

For some parents, those measures have not eased concerns. Kristan Banks, whose 10-year-old daughter attends a district charter school, said her family will keep her home until security changes are made. Banks questioned the value of having officers on site only during the busiest arrival and dismissal periods.

“I’m not going to participate in normalizing these events,” Banks said.

A petition launched by Silver Rail parent Trey Heiss had drawn more than 1,500 signatures by Tuesday night. It calls for school resource officers at each of the district’s roughly 30 schools, routine security reviews, a parent-led safety committee and support for students experiencing mental-health challenges.

Heiss said the officer assigned to his daughter’s school covered multiple schools and could not be expected to respond effectively to a shooting across them. He hopes families’ concerns will be addressed at the school board’s next scheduled meeting, Nov. 10.

His daughter, a second grader at Silver Rail, was at school during the attack. Heiss spent four and a half hours at Journey Church, the district’s reunification center, waiting to learn her status. As of Tuesday, he said, families had been told only that Silver Rail would remain closed indefinitely.

The 16-year-old attacker, a former Silver Rail student, entered the school by shooting his way inside and opened fire in a special education classroom, police have said. A teacher who was not injured tackled him. A parent who was passing by pursued the teen into the classroom and fatally shot him. Four people — three children and a teacher — were killed, and another educator and a student were seriously injured.

Some families are choosing to return while carrying fear with them. Amy Banton’s 10-year-old son, Wallace, attends Highland Magnet School and went back to class Wednesday. The day before, the two made art and wrote notes for Silver Rail families at a free event at the Deschutes Public Library’s Central Library.

Banton said she believes in the safety plans in place but remains worried about what could happen. The gathering also honored 5-year-old Rhoam Summer, one of the children killed. Police said the families of two other slain children, ages 8 and 11, had asked that their names not be made public.

The district’s emphasis on routine and connection is unfolding alongside parents’ demands for accountability and more lasting safety measures. Heiss said he worries that a quick return to normal could leave those demands unanswered.
