PASCO COUNTY, Fla. — It was an emotional day of testimony Friday, the fifth day of the Curtis Reeves trial, as his daughter took the stand.

Reeves, 79, is facing charges of second-degree murder and aggravated battery and could spend the rest of his life in jail if found guilty. The defense claims Reeves shot Chad Oulson in self-defense after an argument at a movie theater in January 2014.

Reeves was 71 at the time of the shooting. His lawyers have tried to show throughout the trial that even back then, he suffered physical ailments.

On Friday, his daughter told the court she moved in with her parents in April 2013 - less than a year before the shootings. She said her parents were still active at that time, but she began noticing changes.

"You hear about their different ailments, but then when I moved in, I started to see all of those things,” Jennifer Shaw said.

Shaw teared up when talking about the physical changes she noticed in her father in the spring of 2013. She said he couldn't pull apart kayak paddles on a trip, bruised easily, and had trouble getting up after he'd sit on the floor to play with her young daughter.

“His fingers would lock up, and sometimes it was just one, and sometimes it was multiple,” she said.

Assistant State Attorney Scott Rosenwasser pointed out during questioning that challenges she mentioned are common for people in their 70s.

“So, on one hand, he's deteriorating so much that you're crying, but then on the other hand, you're indicating that in 2013, they lead a fairly active lifestyle, right?,” he asked, with Shaw saying, “Correct.”

Rosenwasser grilled Shaw about the activities Reeves still took part in - from archery and shooting sporting clays to household chores, like yard work and washing the car. He said talks about Reeves’ ailments didn’t match up with what happened the day Oulson was shot.

“Did you see the video where he fired the weapon?” he asked. “And did you notice how fast he moved in that video, which would be contradictory to the picture that you're painting?"

"I saw the video,” Shaw said. “I don't recall the speed in which he moved."

Multiple witnesses who were in the movie theater the day of the shooting took the stand throughout this week.

All of them told the court they did not notice Reeves having any trouble walking through the theater in the minutes leading up to the shooting.

LEAD CRIME SCENE DETECTIVE TAKES STAND

A Pasco County Sheriff's Office detective who was the lead crime scene detective took the stand Friday.

The defense questioned how much prior experience he had with cases like this and the way the investigation was conducted.

Aaron Smith testified he became a detective with the major crimes unit in December 2013, just one month before the shooting.

He testified that he interviewed Curtis Reeves' wife and son at the theater, but didn't tape those interviews because he didn't have his recorder with him.

How surveillance footage from the theater was collected was also questioned during Friday's proceedings.

Smith said management told law enforcement they couldn't view the video immediately because they were backing it up, which would take several hours.

He testified he told a detective with the Cyber Crime Unit that he could take care of picking up a copy of the video.

On Thursday, Pasco County Sheriff's Office Detective Allen Proctor spent about two hours being cross-examined by the defense.
