The 12-year-old son of one of the four law enforcement officers killed Monday in a shootout in Charlotte, North Carolina, has written a tribute to his father, the Charlotte Observer reports.

Theo James Elliott, son of Officer William “Alden” Elliott of the North Carolina Department of Adult Correction wrote:

William “Alden” Elliott Obituary

My daddy is a hero.

He died getting the bad guys, that’s what he was good at.

He is a Marine.

He is a Police Officer.

He is kind and patient.

He keeps my mom and I safe.

He is my daddy; the best daddy.

We love playing video games together. He really likes Mario, Zelda, and Metroid Return of Samus.

We collect Pokemon cards. I have a Charizard that he helped me get graded.

He and I have watched every Star Wars movie and series.

My daddy loves playing and watching baseball. His favorite team is the Dodgers.

He is an expert marksman, perfect score every time.

For my 12th birthday he bought me a dirt bike. He bought himself one too, so that we could ride together.

I will learn how to ride it and we will ride together one day, Daddy.

He was the best man I will ever know.

And I hope to be just like him.

Officer William “Alden” Elliott, 46, was a 14-year veteran of the Department of Adult Correction. He was one of three members of a U.S. Marshals Fugitive Task Force killed Monday while serving a warrant in east Charlotte on a felon wanted for possession of a firearm. A Charlotte-Mecklenburg Police officer was also killed in the same gunfight after responding to back up the task force. Four other officers were wounded or injured in the same incident.
