Dallas Police Officer Credits Experience to Stopping Armed Robber

A Dallas police officer credits 10 years of experience and training on the police force to her quick-thinking in stopping a robbery in progress late Tuesday night.

Sr. Cpl. Cassie Dotsy arrested an armed robber after he fired shots both inside and outside a Wal-Mart at 7401 Samuel Boulevard.

"I heard the shots and I knew that they were close," said Dotsy.

She looked up from filling out an accident report to see shoppers running out of the store and knew something was wrong.

Dallas police said the suspect, later identified as 36-year-old Marcus Booker, walked into the store, pointed a gun at a cashier and demanded money. Before the cashier could react, the man started shooting at the floor and cash register.

“I didn’t have time to think about anything else,” Dotsy said about jumping into action when she saw the suspect run out of the Wal-Mart. “I saw the citizens running. I saw kids. I heard shots and I just reacted, to what I say is natural when you’re in the profession that I'm in."

Dotsy said shoppers helped point out where the man was running as he ducked around vehicles in the parking lot and fired two more shots.

Eventually, police said the suspect listened to Dotsy’s verbal commands and put down his gun.

Booker was eventually arrested and booked in the Dallas County Jail for aggravated robbery.
