DORAL (CBSMiami) – After several days of searching for the shooter who opened fire at a CityPlace parking garage in Doral, police have arrested 32-year-old Alex Arnaud in Homestead.

Arnaud bonded out after spending just one night in jail. He walked out of jail Thursday, smiling, looking carefree.

He mumbled, “The truth will set you free,” as he walked to his car. Witnesses of the shooting Sunday night say it doesn’t seem like he’s taking his actions very seriously.

The woman who captured the viral video is Nina Okoroji. She was walking to her car to grab a sweater when she witnessed a fight.

“They start fighting, a dude runs up and punches her,” she says.

Nina says she saw a man punch a woman. That’s when she pulled out her phone and started filming.

“They drag her hair and then they pull her down the stairs,” she recalls.

According to investigators, a man was following a woman, refusing to leave her alone. That’s what led to the fight between two groups of people.

“They got kicked out of a club and were being followed by the other party,” says Okoroji.

During the fight on the staircase, someone was struck with a bottle. That’s when police said, Arnaud, pulled out a gun and fired.

“I was in shock but when I heard the second gunshot – that’s when I took off,” said Okoroji.

Nina continued to film as she ran to a safer spot.

“It was super terrifying. To be so close and see the gunshots I was scared for my life. I didn’t know if he was going to start shooting at me since I was recording it,” she said.

Arnaud, who’s facing a felony attempted murder charge, bonded out and quickly left the county jail.

“The truth will set you free,” he said, as he walked to his car.
