In a case that federal prosecutors trumpeted as the largest ever of its kind, 10 members and associates of the Florencia 13 street gang were convicted Monday on a range of federal charges, including racketeering, drug trafficking and attempted murder.

The verdicts followed a 3 1/2-month trial in U.S. District Court in Santa Ana in which prosecutors told jurors of a widespread criminal enterprise directed by Mexican Mafia members, both on the street and in prison.

The gang controlled drug distribution in unincorporated areas south of Los Angeles and in Huntington Park and collected rent from people who wanted to commit crimes in the area the gang controlled, prosecutors alleged.
