By 1974, a 23-year-old Rosenberg began selling cocaine and quaaludes, again backed by DeMeo. He acquired the Quaaludes through a pharmacist connection, as well as the cocaine, which at the time could be prescribed for medical purposes. Through this pharmacist, Chris Rosenberg and the rest of the early DeMeo crew met 22-year-old Andrei Katz, a man who became what was most likely the crew's first murder victim. When Katz was arrested due to a stolen vehicle he purchased from the crew, he blamed Rosenberg for his predicament.
