While in jail, he built up his street credibility. These criminal offences landed him in jail for a few weeks. Sometime after the year 1987, he began going by the name 'OG Loc', and started committing petty crimes, mostly traffic violations. Sweet advised him to leave the ghetto and attend college, but Jeffrey was set on becoming a rapper. Jeffrey lacked the physical capability to join the Families, but was still enamoured of the gangster lifestyle. Jeffrey grew up on Grove Street, where he became friends with several members of the Grove Street Families, including Sweet Johnson and Big Smoke.
