Right goes wrong

He was a teacher of Spanish
A fine man of many skills
Also a life of Wine Women
And Fun.
Had a gun.
For protection, naturally
But also having to do
With his other life
Dealing with Drugs
And a band of Hombres.
It is when he started
To think himself big
And bigger that he hit a snag,
Aimed tooooo high
And ended up
In a body bag.
