The Florencia 13, also known as South Side Florencia 13, Florence Gang, F13 is an American criminal street gang based in Los Angeles, California, composed mainly of Mexican-Americans. The gang is named after the Florence area of Los Angeles County, controlled by the Mexican Mafia.[7] They are involved in drug smuggling, murder, assault and robbery.

History
The Los Angeles County Sheriff’s Department, DEA & ATF began targeting Florencia 13 gang members for their roles in racially motivated attacks on African-Americans.[8] Court testimony and the judges ruling found that F13 members had targeted African-Americans based purely on race.[8] At certain times, Florencia 13 leaders ordered killings of the East Coast Crip gang, according to Los Angeles County Sheriff Lee Baca.[9] The conflict was triggered by the theft by East Coast Crips of a large amount of drugs from Florencia 13 members. This resulted in the Mexican Mafia putting a “green light” out on the East Coast Crips.[10] On January 13, 2019, two people were shot and wounded outside the Fashion Place Mall in Salt Lake City, Utah, after an argument erupted between Florencia 13 and Norteños members. Two male Florencia members, aged 19 and 20, were arrested for involvement in the incident. The two suspects were also charged for a shooting at a group of people at a Taylorsville, Utah cemetery on January 6, which did not harm anyone.[11] On October 6, 2019, four men, ages 20s to 50s, were killed and five injured at KC Tequila, a Hispanic-themed bar and restaurant in Kansas City, Kansas. It was among the deadliest acts of violence in modern Kansas history. The suspects were alleged members of Florencia 13, and are facing murder and attempted murder charges.
