The 71-year-old former police officer accused of fatally shooting a man at a Wesley Chapel movie theater Monday is scheduled to appear before a judge today.

Curtis Reeves is being held at the Pasco County Central Detention Center in Land O' Lakes jail on a second-degree murder charge. He is set to appear in court this afternoon and could have bond set.

According to the Pasco County Sheriff's Office, Reeves shot and killed Chad Oulson on Monday in front of about 25 people in the theater.

Deputies said Chad and Nicole Oulson got into an argument with Reeves and his wife, who were sitting behind them during previews for the 1:20 p.m. showing of the war movie Lone Survivor.

Officials said the arguments started over the Oulson's using a cell phone just before the movie started.

Pasco Sheriff Chris Nocco said Reeves asked Oulson to stop several times, and that at one point he got up and left the theater, then returned to his seat.

Nocco said Oulson then asked if Reeves had reported him to theater management for using his phone, and the two men began to argue.

At some point, Reeves shot Oulson, 43, in the chest, Nocco said. He said Nichole Oulson put her hand up to her husband's chest as Reeves shot him, trying to stop the bullet.

Nocco said two off-duty nurses, who were also in the theater, began performing CPR and tried to save Oulson. Both victims were transported to local hospitals, but Chad Oulson died. His wife was treated for a gunshot wound to her hand, authorities said.

An off-duty Sumter County deputy was inside the theater at the time, Nocco said. Authorities said the deputy secured the gun and held Reeves until deputies arrived and took him into custody. No other injuries were reported.

Both men are being described as kind and stand-up citizens.

According to Tampa Police, Reeves retired from the department on Sept. 30, 1993 as a captain. Later, he was the director of security at Busch Gardens until 2005.

A TPD spokesperson said he was instrumental in establishing the department's first Tactical Response Team.

Meanwhile, neighbors in Reeves’ Brooksville community were shocked at the news.

"A very nice guy," Bill Costas said. "Always smiling. I've never seen him angry. Very helpful. If I needed help with something he was always there to help. Totally different guy.

"It just doesn't make sense to me. Not from what I know of him.”
