Deputy Abigail Rose Bieber "Abby"
30 YEARS OLD ·
Saint Augustine,
Florida
Abigail “Abby” Rose Bieber was 30 years old, a Hillsborough County Sheriff's Deputy, an avid runner, a baker, and a deeply devoted public servant. Abby built meaningful connections throughout her community and was working toward her dream of becoming a detective specializing in crimes against children. Outside of work, she cherished trips to the Dunedin Causeway with her mother, loved baking treats for her family, and shared her life with her beloved dog, Louey.
Born March 14, 1991, in Washington, D.C., Abby moved from Bethesda, Maryland, to Florida in 2016. She served Hillsborough County for four years as a sheriff's deputy, primarily in patrol, while also completing undercover assignments and working with children through the Boys & Girls Club. Shortly before her death, Abby had been approved to join HCSO's Street Crimes Unit, a step toward her goal of becoming a Special Victims detective focused on crimes against children. Abby was an avid runner, enjoyed visiting the Dunedin Causeway with her mother, and loved baking and sharing what she made with her family.

Civil litigation
Abigail's father brought wrongful-death/civil-rights-related claims concerning HCSO's alleged handling of Leyden's prior conduct. The federal court later dismissed some claims and remanded the remaining matter to state court. Middle District Court FL
LEGAL / SYSTEM RESPONSE
Abigail and Leyden were both employees of the Hillsborough County Sheriff's Office. Following Abigail's death, allegations emerged that Leyden had been accused of violent or threatening behavior involving other women years before the homicide. In 2026, Abigail's father, acting on behalf of her estate, brought civil claims against the Hillsborough County Sheriff alleging that the agency had inadequately handled and concealed prior complaints involving Leyden. The Sheriff's Office has contested the claims. In September 2026, a federal judge dismissed some federal claims, allowed other issues to proceed, and remanded the remaining case to state court. The civil litigation remains separate from the criminal determination that Leyden killed Abigail before taking his own life.
