Grandmother fatally punched in French Quarter; brother has 'no earthly idea why'

Johnson Street, 61, got into an argument with Jeremiah Mark, 23, in the 100 block of Royal Street on April 18 at about 7:45 p.m. Details about the argument haven’t been available, but Mark punched Johnson Street in the face, causing her to fall backward and hit her head on the concrete, police wrote in a sworn statement filed in Criminal District Court.

She was taken to University Medical Center, where staffers diagnosed her with a traumatic brain injury. She died April 20, and her death was classified a homicide after an autopsy two days later, police said.

They booked him with manslaughter, which Louisiana law defines as an unintentional yet unjustifiable killing.
