The Baton Rouge Area Foundation announced Monday that it had set up an online site for its First Responders Fund — a fund created in 1988 offering relief to wounded officers and their families. 

The fund is overseen by law enforcement leaders in Baton Rouge and will be used to help families of the officers killed in the line of duty.

Other pages have popped up on GoFundMe to provide direct support to families of victims. 

Jackson, a Baton Rouge police officer with 10 years of service and a new father, had already generated almost $50,000 after his GoFundMe page had been posted for only 20 hours.

"Montrell was a highly regarded police officer in the Baton Rouge Police Department, and most importantly, a beloved husband, father, son, brother and friend," according to the GoFundMe page , which was set up by Melissa Rose. "Words cannot describe the devastation that we feel right now, and would ask that those who are able to please contribute to this meaningful cause in order to assist Montrell's family financially during this time of mourning."

A GoFundMe page for Gerald, another Baton Rouge police officer, was set up by his cousin, Jaylan Gerald, who described him as a "beloved husband, father, and a great man all around."

Garafola's GoFundMe was created by a family member who expressed concern about his four children, in particular the three youngest who live at home. He had one 21-year-old child who lives in Texas. 

"Upon speaking with my nieces and nephew, ages 7, 12 and 15, the one question that remained constant from them was where were they going to live and how were they going to survive without the support of their father," James Cooper wrote on the page. "At this age, they should be more concerned with mourning the loss of their father, who was their sole provider and loved them unconditionally, instead of worrying about where they go from here."

The three law enforcement officers were shot and killed Sunday by Gavin Eugene Long, 29, of Kansas City, Missouri, at a Baton Rouge convenience store. Long had for several days been posting anti-police rantings on social media.
