The initial shock of living through the worst mass shooting in modern U.S. history is subsiding more than 10 days after 49 people were killed at Orlando's Pulse nightclub.

On Thursday, a new assistance center for shooting victims opened, following by an evening street party planned by the Pulse nightclub owner as a way to show the community's resiliency.

The party will have a Latin theme, since it was "Latin night" at Pulse on June 12, when gunman Omar Mateen opened fire. In addition to those killed, another 53 patrons were wounded.

Orlando Mayor Buddy Dyer says the new victim's assistance center, located about a mile from Pulse, will stay open as long as survivors and family members of victims need help.
