Summary
Richard “Rich” Porter was killed in early January 1990. His body was found in the Bronx with more than $2,000 in cash, causing investigators at the time to discount simple robbery as the obvious motive.
Immediate Context
Porter’s younger brother William had been kidnapped on December 5, 1989 and remained missing. Contemporary investigators therefore considered whether Rich had been killed while privately attempting to negotiate his brother’s return.
Later Attribution
Later participant accounts and Martinez-related reporting attributed the killing to Alberto “Alpo” Martinez. The final encyclopedia page should cite the strongest available admission, plea, court filing, or recorded interview and distinguish that later attribution from what investigators publicly knew in January 1990.
