ORLANDO, Fla. -

Both the state and defense have rested in the trial against Timothy Davis Sr., a former Orlando police officer accused of shooting and killing his 21-year-old son in Apopka more than a year ago, has taken the stand in his own trial.

Timothy Davis Sr. was charged with second-degree murder in the shooting death of Timothy Davis Jr. during an argument on October 1, 2011. He took the stand on Wednesday afternoon, describing the day leading up to the shooting of his son as "great."

"And then after he punched me he just picked me up, and tackled me," Davis Sr. said.

Tarsha Davis, wife of Timothy Davis Sr., gave an emotional testimony on Wednesday having to be escorted out of the courtroom after being asked how many children she has.

Tarsha Davis told jurors about the fight between Davis Sr. and Davis Jr.

"I grabbed his shoulders and I pulled him back and he yanked back up and he kept pounding on him," Tarsha Davis said. "I said if you don't stop I'm going to call the police and he wouldn't stop."

A couple of witnesses were called to the stand on Wednesday, testifying that they saw Davis Sr. after the shooting with a busted lip and a swollen face.

Before the state rested, jurors also watched a slowed down version of the surveillance video that showed Davis Sr. shooting Davis Jr. at their Apopka home, but the defense says the video doesn't show what happened leading up to the shooting.

The video does show Davis Jr., Davis Sr. and Davis Jr's girlfriend Georgina Edmund at the front door of the home. Edmund and Davis Jr. were fighting about custody over their son and Davis Jr. became angry when Davis Sr. tried to intervene.

Court resumes Thursday morning at 9:40 a.m. and they will give closing arguments.
