This north-south split also caused street rivalries between gangs to be set aside while in prison. The split acted as a bonding agent for Mexican gang members while incarcerated because now they had a common enemy. By the late 1960s, a gang ethic had been formed and there were certain rules that bad to be followed. A standard gang practice and custom had been developed.
The 1970's
In 1970, the now well-known Mexican Mafia member, Joe "Pegleg" Morgan was recruited into the gang. Morgan was highly respected and feared in and out of the correction system. Though he was a member of a Mexican street gang, he was of Slavic decent. Morgan however, spoke, read and wrote Spanish fluently. Raised in Los Angeles, he took pride in the Mexican heritage. He earned the reputation of being a violent, ruthless and cunning inmate through his association with the Maravilla street gang. According to Sgt. Richard Valdemar, Morgan had also established strong ties to other L.A.-based street gangs, the Italian Mafia and with the drug traffickers from Mexico.
By 1972, Morgan had become the figurehead leader of La Erne. Also by this year, Morgan had solidified the alignment between the Mexican Mafia and the Aryan Brotherhood. This was done in order to strengthen the Erne power base, because the Black Gueril1a Family had also formed. La Erne was preparing for a war.
La Eme flourished in the 1970s when it started to exert its influence on the streets. Mexican Mafia parolees were held with a high degree of respect by street gang members. These parolees would routinely Ca1TY out Erne assigned hits. Between 1976 and 1977 there were more than 30 Erne executions on the streets. One victim was a California State Senator's aid, who was assassinated in Los Angeles.
