CLEARWATER, Fla. -- Civil Rights Attorney Benjamin Crump is calling for the arrest and indictment of the gunman who shot and killed Markeis McGlockton outside of a Clearwater convenience store.

"It's ludicrous how you can claim that you have feared for your life, but yet you approach and start the confrontation with the individual," Crump said in a Thursday morning news conference.

Crump stood before the Pinellas County Courthouse with his client, Britany Jacobs, McGlockton’s longtime girlfriend and the mother of his three children. McGlockton's parents and their attorneys were also present.

"We were all introduced to this stand your ground law with Trayvon Martin in Sanford, Florida, and then you had Corey Jones in West Palm Beach, Florida, and now you have Markeis McGlockton in Pinellas County, Florida," said Crump. 

Surveillance video showed the 28-year-old McGlockton shoving Michael Drejka, 47, to the ground after Drejka confronted Jacobs for parking in a handicapped spot outside the Circle A Food Store on Sunset Point July 19.

Drejka shot McGlockton in response in front of his three young children. McGlockton later died of that wound.

Jacobs hasn't told her children their father is dead. "It's hard for me to even say where the father is right now, and we need justice," she said. 

"It was an uncalled for murder and my son didn't deserve to die like this, period," said Michael McGlockton, McGlockton's father. 

Pinellas County Sheriff Bob Gualtieri has not arrested Drejka because he believes the shooting might be covered under the stand your ground law, which allows citizens to use deadly force if they believe their lives are in danger. Michele Rayner, attorney for McGlockton's parents, says this shooting does not fall under that law. 

"We're demanding that there is justice," Rayner said. "We're demanding that there are charges filed against Michael Drejka."

The state attorney says the case is still under investigation. McGlockton will be laid to rest on Saturday.
