It has been a day of unspeakable tragedy concerning gun violence after an elementary school shooting in Connecticut, and now a report out of Memphis tells of more families in mourning.

Two police officers were involved in a shootout when they arrived at a home to serve a drug-related search warrant early this morning; Martoiya Lang and William Vromah were subjected to gunfire when they showed up, and returned fire on the suspects, who have yet to be identified. Lang, a mother of four, died from her injuries. Vromah was seriously injured and is currently in the care of Regional Medical Center.
