Curtis Reeves is accused ofin a Florida movie theater on Monday, after an argument over Oulson texting during the movie previews.
Eye witnesses suggest that there had been no physical violence before the shooting. At worst, words had been exchanged and some popcorn had been thrown.
Reeves, a 71-year-old retired police officer, is currently facing charges of second-degree murder.
Now a woman has come forward to say that she also had an altercation with him in the same Cobb Grove 16 movie theater in Wesley Chapel, Fla., a couple of weeks ago.
As WTSP-TV reported on Tuesday, Jamira Dixon said that Reeves had harassed her when she was texting during previews.
Speaking at a press conference with her husband, Dixon said: "He became just upset about the whole situation and kept staring and giving us dirty looks."
She also claimed he stood up and shouted at another person who was apparently annoying him by texting.
When she heard about the shooting, she was in her car. "I had to pull over the car because it could have been us," she said.
Dixon shared her story with detectives and may be called as a witness in Reeves' trial, reported WTSP-TV.
In Reeves' first court appearance on Tuesday, his lawyer described his client as the victim and Oulson as the "aggressor."
The local Pasco County Sheriff, Chris Nocco has, however, declared that Florida's notorious "stand your ground" law doesn't apply in this case.
Reeves has been denied bond.
