BROOKLYN - Police have arrested a Brooklyn man after they say he admitted to murdering his stepdaughter. Police say the incident occurred yesterday afternoon outside the girl's home on 102nd Street. They say Lakeshia Seymour, 19, was bludgeoned to death by her stepfather, Jean Simon, 53, who lives in the same residence. Sources tell News 12 Brooklyn that Simon purchased a hammer at a local store, returned to his home and proceeded to hit Seymour until she died. Simon then fled the scene, but was shortly thereafter arrested in Queens after crashing his car. Police say there was no domestic violence history at the home, and that Simon has been charged with first-degree murder and criminal possession of a weapon.
