HOUSTON -

Testimony wrapped up in a downtown courtroom in a trial that all started with Grammy-winnning singer Patti LaBelle's bodyguard allegedly assaulting a man at Houston's Bush Intercontinental Airport.

Both sides rested their cases Friday afternoon after Efrem Holmes took the stand in his own defense. He told the jury he believes he used appropriate force as he came to the aid of LaBelle's son, Zuri Edwards.

Efrem Holmes is charged with assault after surveillance video showed him pushing a former West Point cadet to the ground back in 2011.

But on Friday, a defense attorney broke down the video frame by frame, digitally enhancing it to try and show the jury Holmes was reacting to King's actions., using an open hand to push King away from Zuri Edwards and not a closed fist.

At one point, the still images brought Holmes to tears.

When an attorney asked Holmes to break down his actions, he said, "I go towards Zuri and Mr. King."

Attorney: Why?
Holmes: Zuri's in danger
Attorney: Why?
Holmes: He's been hit by Mr. King.

He later went on to say, "I don't regret what I did. I regret Mr. King was injured."

The testimony comes one day after Patti LaBelle herself testified, telling the jury Holmes took action only after King tried to get in her limo and punched her son.

Zuri Edwards also took the stand Friday telling the jury he heard King yelling expletives about his mother.

But under cross-examination, prosecutors questioned why Edwards didn't communicate that to police until months later when a civil suit was filed.

Closing arguments are scheduled for Monday.
