Rossi was raised by his parents, also little people. During his childhood, he lived in two very disparate neighborhoods: the San Fernando Valley, a wealthy area in Greater Los Angeles, and Nickerson Gardens Housing Projects in Watts, a poor area in South Central Los Angeles, where he lived with a family friend to avoid conflict at home. By the age of 15, he was living on his own.
In 1987, Rossi graduated from Fremont High School. He joined the neighborhood Blood gang while living there.[2] That year, he was involved in a gang-related shooting and convicted of felonies including attempted murder and assault with a deadly weapon. He was sent to the California Youth Authority and was later transferred to Folsom State Prison to serve a total sentence of 10 years, 10 months and 10 days.[3]
