Who deleted database

How can I find out who deleted a database?  I know it is not best practice to allow multiple users  sysadmin access or dbo access.  

I have tried the code below and it did not tell me.

Any other suggestions?

DECLARE @path varchar(256) 
 
SELECT @path = path 
FROM sys.traces 
where id = 1 
 
SELECT TextData, HostName, ApplicationName, LoginName, StartTime, DatabaseName 
FROM fn_trace_gettable(@path, 1) 
where TextData is not null 
order by startTime desc

Select allOpen in new window
