LOS ANGELES - A gunman killed eight people and wounded several others before killing himself in a late-night shooting Thursday at a FedEx facility near the Indianapolis airport — the latest mass shooting on an already long list in 2021 after a lull during the COVID-19 pandemic.Authorities continued to search for a motive in the wake of the shooting in Indianapolis.Officials said at a news conference Friday that they had not yet identified victims, in part because the coroner’s office had not yet been able to go onto the scene.
