Clifton Sparks, a 31-year-old Black / African American man, was found unresponsive in the 1800 block of B Avenue NE in Cedar Rapids, Iowa, in the early morning hours of February 3, 2014. Emergency responders pronounced him dead at the scene after investigators determined he had sustained a traumatic injury; his death was investigated as a homicide.

Detectives developed a suspect in the case, Robert L. Nash IV. Charges were brought against Nash, and the legal process resulted in a conviction and a 45-year prison sentence for his role in Sparks’s death.

Does anyone have memories of that Cedar Rapids neighborhood or information that could add to the timeline of Clifton Sparks’s last hours?
