There is a defaul trace managed by SQL Server in a log file under c:\Program Files... You can view this file by SQL command. For example to see the file log_19.trc you can fire command like

SELECT * 
FROM fn_trace_gettable
('C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\log_19.trc', default)

This will probably show when and who dropped the database. More information can be found Here...
