The details were revealed a day after police announced that it was likely Joseph Wamah Jr., 31, had been killed in the early hours of July 2, and not during the larger July 3 attack, as police had initially thought.

The dispatch error has people in this heartbroken neighborhood wondering if the mass shooting the following day could've been prevented.
