Q: Trash Wont delete locked items.

I have an application in the trash that is locked and I am unable to delete it. Ive tried using single user mode and terminal to erase it using the command rm -rf ~/.Trash/* but that has not worked. The app has all the package contents removed and is 0KB but I am unable to remove it.

Thanks

I have a MacBook Pro with Retina 13" on OS X 10.10.3 (It also wouldn't erase on other previous software version)
