What can i do to get by adult boxer to stop chewing everything while im not home?

i bought a crate yesterday in hopes to solve my problem. i threw in a kong toy, a rawhide, and some other toys; it worked hroughout the morning while i was at work for 7 hours. then i went to a cl for 3 hours in the evening, and when i got home she somehow moved the crate closer to the bed and tore up my comforter, clothes, and sheets.
