"Other items will be preserved by MSU Archives and the MSU Museum," the university said.

"It’s hard to do this," said Chris Hewitt, operations coordinator at the MSU Surplus Store and Recycling Center.
"You read a lot about shootings on campus, but you don’t think about the whole having-to-clean-up process," Hewitt told The Detroit News. "It’s literally our job to clean up campus, and this is something that was going to happen."
A senior, Emma Holfer, cried near the statue as she explained why she volunteered.
"I thought it would just be a good thing to do in remembrance of everyone," she said.
Separately, Michigan State said degrees would be granted posthumously to Arielle Anderson, 19, of Harper Woods, Brian Fraser, 20, of Grosse Pointe Park and Alexandria Verner, 20, of Clawson.
