Could it be "Menzies"? Check with Menzies' tour and transfer company in Corozal...011-501-422-2725...if it's not them, I am guessing they know who it is!
I am not familiar with any Mensies out of Belmopan. Maybe Katie knows or post it on the other message board at belizeforum.com - that board gets more locals and mainlanders.
