Clark County and the Metropolitan Police Department will co-host a 1 October Sunrise Remembrance ceremony at 7:30 a.m. Sunday at the Clark County Government Center Amphitheater in downtown Las Vegas.

The annual ceremony recognizes those slain at the Route 91 Harvest festival shooting on Oct. 1, 2017, in the worst mass shooting in modern U.S. history.

Among the list of speakers is Nevada Gov. Joe Lombardo, who was the sheriff of the Metropolitan Police Department at the time of the shooting. Current Sheriff Kevin McMahill and Steve Gomez, the father of 1 October victim Angela Gomez, also are expected to speak.

The ceremony will be aired on Clark County’s YouTube and Facebook pages.
