Prosecutors charged a white man with manslaughter in the death of an unarmed black man whose video-recorded shooting in a store parking lot has revived debate over Florida's “stand your ground” law.

Michael Drejka, 47, has been charged with the July 19 death of Markeis McGlockton outside a Clearwater convenience store, Pinellas County State Attorney Bernie McCabe said. Drejka was being held at the county jail on $100,000 bail. It was unknown if he had an attorney.

At a news conference Monday afternoon, relatives of McGlockton said they were pleased with the charge.

“I know this is going to be a long road,” said Michael McGlockton, the victim's father. “We are up for the task. I just hope for a good outcome.”

Family attorney Michele Rayner said “the ultimate goal is conviction,” and that she believed manslaughter was the correct charge. She also noted that Monday was bittersweet.

“It's little Markeis' first day at school,” she said, referring to McGlockton's 5-year-old son.

McGlockton's girlfriend, Britany Jacobs, who was seated in the couple's car with two of their children, ages 3 years and 4 months, said Drejka confronted her for being parked in a handicapped-accessible space. McGlockton, 28, had gone into the store with young Markeis.

Video shows McGlockton leaving the store and shoving Drejka to the ground. Seconds later, Drejka pulls a handgun and shoots McGlockton as he backs away.

In court documents, McCabe and Pinellas Sheriff's Detective George Moffett cited three other drivers who said Drejka threatened them during confrontations that preceded his run-in with McGlockton. Two of them said he displayed a gun.

McGlockton family attorney Benjamin Crump, who gained national prominence representing the family of Trayvon Martin after the black teen's fatal shooting by a Hispanic man in 2012, said in a statement Monday “it's about time” Drejka was arrested.

The family, civil rights groups and others had been holding protests demanding he be charged, saying if Drejka had been black and McGlockton white, deputies would have arrested Drejka immediately or shot him.

“This self-appointed wannabe cop attempted to hide behind 'Stand Your Ground' to defend his indefensible actions, but the truth has finally cut through the noise,” Crump said.

Pinellas County Sheriff Bob Gualtieri originally declined to charge Drejka, saying one day after the shooting that the man was protected by Florida's stand-your-ground law. The sheriff passed the case to prosecutors for a final decision.

The law says people can use deadly force if they believe they are in imminent danger of death or great bodily harm and have no obligation to retreat. Under a change made by the Legislature last year, if a suspect raises a stand-your-ground defense, prosecutors must prove the law doesn't apply.

Gualtieri said in a statement Monday that he supported McCabe's decision.

Store security video shows the confrontation began about a minute after Jacobs pulled into the handicapped-accessible spot. Jacobs told Moffett that two trucks blocked her from getting to other spaces. McGlockton and young Markeis got out and entered the store.

Drejka pulled up in his SUV seconds later, parking perpendicular to Jacobs. Drejka got out, walked to the back of Jacobs' car, looked at the license plate, and then went to the front, where Jacobs told Moffett that Drejka began yelling at her.

The video then shows McGlockton leaving the store, walking toward Drejka and shoving him with both hands. Drejka lands on his back and McGlockton takes a step toward him. Drejka sits up, pulls his gun and points it at McGlockton, who takes three steps back until he is about 12 feet away. Drejka fires, hitting McGlockton, who runs back into the store clutching his chest. Witnesses said he collapsed in front of young Markeis, who was waiting inside.
