Ruthanne nodded and made a note. I glanced at Detective Okonjo. She was sipping her coffee.
"You moved Isidore's locker on September 29th," Ruthanne said. "Why?"
"A maintenance issue with the bank of lockers in the science wing."
"Which locker was he moved to?"
"I'd have to check."
"I checked," Ruthanne said. "It's locker 1144, in the east hallway. Which is, I'm told, the only locker bank in Halverton East that isn't within view of a security camera." She let that sit. "Was that intentional?"
"Ms. Ebbesen, I don't see the relevance—"
"Withdrawn," said Ruthanne pleasantly, and turned to Bobbie.
"Mrs. Tillotson. You do a compliance walk every evening."
"Most evenings."
"What time?"
"Around nine. Sometimes later, if I've had a meeting."
