Door lock is stuck

I need some help. I got a call from one of my neighbors that a couple guys had the hood up on my Mustang. Said when he went over and asked them what they were doing they said "We have a car just like this were working on and wanted to see how a bracket bolts on." Also said they didn't see anything wrong with what they were doing.

Long story short nothing is missing from the bay BUT when they opened the door to pop the hood they broke the door handle off. The locks don't work but the driver side has the lock engaged now, not sure how it happened. Now I can't get the door to unlock so I can shut the door, key wont budge it (or the passenger side) and pulling on the inside handle will open the door mechanism but wont over-ride the lock.

Any help? The whole situation is just a little messed up and I just want to get the door to where it will shut. Help is majorly appreciated.

Thanks Hissin I'll check that out.

No.11, he war hardly being naive he had a few choice words for them when he called me and... "politely" told them they should leave. That sort of thing just doesn't happen around here so when it does it's easy to see through the lies.
