Michael Davon Hayden Jr., 21, was fatally shot on a Brooklyn street in the East New York neighborhood on November 21, 2014. Hayden, who lived with sickle cell anemia, was killed in an act of gun violence that devastated his family.

The case remained unsolved for about two and a half years while detectives pursued leads. In May 2017 investigators identified and arrested 23-year-old Nivon Spignardo in connection with the shooting. He was indicted on second-degree murder and two counts of second-degree criminal possession of a weapon.

A jury trial followed; in March 2018 Spignardo was found guilty of murder and one count of criminal possession of a weapon and sentenced to 22 years to life. Does anyone have information about Hayden’s life in East New York or details from that night that could add to the record?
