Cynthia Seith, 54, a woman of White/Caucasian ethnicity, was found shot on the sidewalk outside the Lucerne Greens Condominiums on Lucerne Boulevard in Greenacres, Florida, in the early hours of July 15, 2025. Deputies were called to the scene around 3 a.m., and the victim—also reported in local coverage as Cynthia Lynn Sciarrone or Sciarrone-Seith—was discovered near her condo days before her 55th birthday. She worked as a Spirit Airlines flight attendant, and neighbors awoke to the quiet complex sealed by crime-scene tape as detectives documented a single gunshot wound to the head.
Detectives from the Palm Beach County Sheriff’s Office opened a homicide investigation that quickly focused on her ex-husband, Richard Edmond Seith, a 53-year-old Stuart ophthalmologist. According to a probable-cause affidavit described in subsequent reporting, the killing followed a contentious divorce in which he had been ordered to pay more than a quarter-million dollars; investigators alleged a pattern of stalking and abuse that culminated with him waiting outside her residence and shooting her as she returned home. The portrait that emerged was of a targeted attack at her Greenacres condo complex—an escalation of earlier threats into a fatal act carried out on a dimly lit sidewalk.
Three to four days after the killing, the Palm Beach County Sheriff’s Office announced the arrest of Richard Seith on a charge of premeditated first-degree murder. A judge later denied him bond, and coverage noted that a grand jury handed up an indictment as detectives detailed the timeline from the 3:22 a.m. “man down” call to the identification of the suspect. Authorities and local outlets emphasized that the victim, Cynthia Seith, 54, had been targeted outside her home, and that the case moved swiftly from a grim discovery to the custody of a named suspect facing the most serious count under Florida law.
Across the community, remembrances described a warm and courageous flight attendant whose life was cut short on a summer night, her final steps ending only feet from her door. In the days that followed, candles and condolences appeared online as friends processed the loss, while investigators pieced together surveillance, statements, and the long shadow of a broken marriage now central to the narrative of an arrest and an impending prosecution.
