A county health official charged with a fatal hit-and-run in Southcrest last month was working the day of the crash, according to county records. Assmaa Elayyat, a deputy director with the county’s Self Sufficiency Services, on Friday, May 22, allegedly veered off the road, struck and killed 27-year-old Katie Osorio while she waited for a bus on 35th Street and National Avenue. Elayyat then allegedly drove away after her car initially got caught in a tree, only to be arrested by police soon after.
