A man who shot and killed another man in Florida this week during an argument over a parking space will not be arrested or charged by the sheriff’s office because of the state’s so-called Stand Your Ground law, the authorities said.

Britany Jacobs, 25, was sitting in a car parked in a handicapped space outside a convenience store in Clearwater, Fla., on Thursday afternoon when a man, Michael Drejka, approached her vehicle and started looking for a handicap permit, Sheriff Bob Gualtieri of Pinellas County said at a news conference on Friday. Ms. Jacobs’s boyfriend, Markeis McGlockton, and their 5-year-old son were in the store when Ms. Jacobs and Mr. Drejka began to yell at each other about whether she was permitted to be in that space, Sheriff Gualtieri said.

In a video recorded on a surveillance camera, Mr. McGlockton, 28, exits the Circle A Food Store, approaches Mr. Drejka and shoves him to the ground. After Mr. McGlockton takes a few steps back, Mr. Drejka, 47, pulls out a gun and shoots him once in the chest.

Mr. McGlockton then retreats back into the store, clutching his chest. He was taken to the hospital, where he was pronounced dead, Sheriff Gualtieri said.
