East Baton Rouge Sheriff Sid Gautreaux said Monday that Baton Rouge was shaken to its core on July 17, 2016, when a gunman killed three law officers in an ambush on Airline Highway.

But the tragedy has also become a turning point for the community, Gautreaux said in a Facebook message posted at 8:41 a.m., the exact time gunshots first rang out that terrible Sunday morning.

"I have witnessed an outpouring of generosity, kindness, love and support." he said. "Kindness opens doors. Hate, prejudice and violence shuts doors. We can’t be a community behind closed doors. I believe our community’s doors are now open wider than ever."

Monday was the anniversary of the fatal shooting of Baton Rouge Police officers Matthew Gerald and Montrell Jackson, and East Baton Rouge Parish Sheriff’s Deputy Brad Garafola.

Gautreaux's statement was accomanpanied by a tribute video honoring the fallen officers.

As the community took time to remember and honor the fallen officers, Mayor-President Sharon Weston Broome ordered all flags on city-parish grounds to be flown at half-staff in honor of the officers.

On this day, Weston Broome said in a statement, "we are reminded of the ultimate sacrifice many of our uniformed officers all too often pay when serving our communities.

"I ask that we continue to honor those lives lost serving and protecting us by coming together as a city and moving forward in solidarity.”
