According to an arrest warrant affidavit, Syed was working as a cashier at A&A Mart on Marsalis Avenue in North Oak Cliff, near the Dallas Zoo, when Horn walked in on July 8.

Video from inside the store shows her placing a bottle of water on the counter. Horn and Syed appear to argue, and then she pulls out a handgun, the police document states.

Horn can be seen on video shooting Syed in the neck and then walking out of the store with the water.

Man killed 2 North Texas gas station clerks over lottery tickets for new apartment: arrest affidavit

Police say the man accused of murdering two North Texas convenience store clerks admitted to the killings and confessed he didn't give them time to comply with his demands. He allegedly did it for lottery tickets to get an apartment.

Syed’s coworkers and two responding officers chased after Horn. 

They captured her in a wooded area a few blocks away. 

A handgun was recovered from the top of a fence post when Horn was arrested.

The affidavit says it was "loaded with a round in the chamber and 10 rounds in the magazine.

In a GoFundMe post written while he was still alive, Syed's son wrote "My father was the sole earner in my family which includes my mom and my two younger siblings who are 5 and 13 years old. My family is facing extreme financial challenges now and are in desperate need of help."

A customer of the Chevron Deli Mart was saddened to learn that Syed did not survive.

"He's a very good guy, all about his job, very serious about his job. No complaints about him, looked out for everyone if you needed help," said Heather Valdez.

Horn was initially charged with aggravated robbery of a business. The charges against her were upgraded after Syed died from his injuries on Monday.

It turns out Horn was already wanted for a shooting three days earlier, on July 5th.

The affidavit from that case says she knocked on the door of a home on Almeda Drive.

"Suspect Horn pointed a handgun at the face of the complainant and pulled the trigger. The firearm jammed and did not fire," reads the affidavit.

When she tried again, the man was shot near the elbow.

The victim in that case survived and told police Horn dropped possible drugs on the ground.

Police recovered synthetic marijuana from the scene.

Horn's criminal record includes a conviction for a family violence assault as well as drug possessionand driving under the influence.

Her bond is set at $1,000,000.
