Floyd E. Preston, a 70-year-old African American man and long-time Alton Park resident, was shot and killed at his home on Sunday, November 24, 2019. A retired employee of Parkridge Hospital and Superior Catering Company and a member of Alton Park Church of Christ, Preston was described as well known in the neighborhood and a Riverside High School alumnus.

Neighbors on Dogwood Drive reported hearing a gunshot; responding officers found Preston shot at the scene and recovered a spent shell casing near his body. The investigation focused on a family member, and Preston’s 68-year-old brother, Marvin Preston, was arrested and charged with criminal homicide. Investigators found two handguns in Marvin Preston’s possession, a 9mm and a 40 caliber. Marvin Preston initially denied involvement and later made statements that incriminated him; the case was bound over to the grand jury and his bond was set at $1 million.

Anyone who knew Floyd Preston or has information about the events at the home that day is asked to come forward.
