Trash won't empty deleted time machine backups
I manually deleted my time machine backups and they won't empty from my trash... I tried deleting it from Terminal but it always says no such file or directory.
When I try to delete them manually from Trash it says: "There are some locked items in the Trash. Do you want to remove all the items, including the locked ones, or just the unlocked items?" to which I said delete all, and nothing happens.
This is what it looks like on Terminal:

Nothing was changed on my macbook. My external drive is plugged into my macbook and I've tried disk utility cleaning and repairing the disks and such but nothing will work. They are taking up about 1GB on my drive and it's more annoying than anything but if it happens again I want to know how to solve it. Please help!
MacBook Pro, OS X Mountain Lion (10.8.4)
