2000 Escort won't come out of park

I parked my car and about one hour later went to leave and it is stuck in park. I checked to see if the break lights were working as it could have been a fuse but they are on. Do you have an idea what it could be or if I can disconnect the cable under to get it out of park and how I can do this? Please help and appreciate all you can to help. Thanks. It only has 28,000 miles on it and was wondering if it could have snapped or froze with cold weather?
