The last of the Park Avenue mass shooter’s final victims was in temporary safety in a panic room, only to be killed when she stepped outside of it during a lull in the gunfire, police sources and authorities said.

Julia Hyman, an employee of Rudin Management and one of four victims of cowardly killer Shane Tamura, was remembered as "delightful" at her funeral.

Rudin associate Julia Hyman was among the five people killed in Monday evening’s mass shooting at 345 Park Avenue.
