Some additional facts from the brief on the case, the search was not just for IBP, that's just what they found:
On October 1, 2003, Jordan, another student at Safford Middle School, along with his mother, requested a meeting with Principal Robert Beeman and Vice Principal Kerry Wil- son. During the meeting, Jordan's mother explained that a few nights before, Jordan had become violent with her and was sick to his stomach. Jordan claimed that the incident occurred after he had taken some pills a classmate had given him. Jor- dan went on to inform Beeman and Wilson that certain stu- dents were bringing drugs and weapons to school. He then gave the administrators detailed accounts regarding the actions of several students, including Redding. Specifically, Jordan informed Beeman and Wilson that Redding had served alcohol to her classmates at a party she hosted at her home prior to the dance in August.2
On the morning of October 8, 2003, Jordan again asked to meet with Vice Principal Wilson. During the meeting, Jordan handed Wilson a white pill and said that Marissa had given it to him and that a group of students were planning to take pills at lunch. Upon learning this information, Wilson took the pill to Peggy Schwallier, the school nurse, and asked her to identify it. Schwallier identified it as "Ibuprofen 400 mg," a pill available only by prescription.
Based on this information, Wilson went to Marissa's class- room and asked Marissa to collect her belongings and accom- pany him to his office. As Marissa got up to comply, Wilson noticed a black planner lying on the desk next to hers. Wilson asked Marissa whether the planner belonged to her and Marissa said no. Wilson nevertheless picked up the planner and handed it to a teacher, who promised that he would attempt to find the owner. Soon thereafter, the teacher discov- ered that the planner contained knives, lighters, a cigarette, and a permanent marker. He promptly communicated this information to Wilson.
