Ennis William Cosby (April 15, 1969 – January 16, 1997), the only son of American comedian Bill Cosby, was murdered on January 16, 1997, near Interstate 405 in Los Angeles, California. He was shot in the head by 18-year-old Mikhail Markhasev in a failed robbery attempt. Cosby was 27 years old. Cosby's death resulted in significant media coverage, public outrage and an outpouring of support for the Cosby family. Seeking the $100,000 reward offered by the National Enquirer, an acquaintance of the shooter provided information that led to Markhasev's arrest in March 1997.
