Witnesses and prosecutors described a different scene.
Mr. Oulson, a Navy veteran and finance manager at a local motorcycle dealership, was on a date with his wife. Their 22-month-old daughter, Alexis, who was with a babysitter at home, was not feeling well.
Prosecutors said the worry about his daughter prompted Mr. Oulson to defy moviegoing etiquette and text the babysitter to see how his daughter was doing. The movie had not started yet while Mr. Oulson texted, they said.
Charles Cummings, who was 68 at the time and had served in the Marines, was in the row ahead of Mr. Reeves during the shooting. He told The New York Times in 2014 that Mr. Reeves was “aggressive” and had been kicking the seat in front of him because “he was agitated” that Mr. Oulson was using his phone in the semidark theater.
Mr. Reeves got up and told Mr. Oulson to quit texting. Mr. Oulson ignored him and continued. Mr. Reeves then left to get a manager, but returned alone.
Mr. Oulson complained about being tattled on, and the two men exchanged more words. Then Mr. Oulson threw a bag of popcorn at Mr. Reeves, who then shot Mr. Oulson in the chest, according to a criminal complaint.
Mr. Oulson’s wife, Nicole, had placed her hand on her husband’s chest and was struck in a finger.
The authorities said Mr. Reeves sat down calmly, put the gun on his lap and stared ahead. An off-duty sheriff’s deputy from Sumter County who saw the muzzle flash snatched the weapon from him. Mr. Reeves resisted at first and then acquiesced, the authorities said.
Ms. Oulson testified that Mr. Reeves was rude and never said, “Do you mind?” or “Excuse me,” The Tampa Bay Times reported.
