Anthony Todt became one of Florida’s most infamous family annihilators after murdering his wife, three children, and family dog inside their Celebration, Florida home in 2019. Prosecutors alleged Todt killed the family over several days before living alongside the decomposing bodies while attempting to avoid financial collapse, criminal exposure, and personal ruin. The case generated intense national media attention because Todt publicly presented himself as a successful physical therapist and family man before the murders were uncovered. Investigators later revealed mounting financial fraud allegations, insurance investigations, and severe personal pressures surrounding Todt before the killings. The horrifying circumstances inside the home, combined with Todt’s shifting explanations and bizarre courtroom behavior, made the case one of the most heavily discussed family annihilation murders in modern American true crime.

Ashley Britt McArthur murdered her friend, 33-year-old private investigator Taylor Wright, near Pensacola, Florida, in September 2017 after Wright sought the return of $34,000 she had entrusted to her for safekeeping.

Cell-phone records, financial evidence and surveillance footage helped investigators reconstruct McArthur's movements. She was convicted of first-degree premeditated murder in August 2019 and sentenced to life imprisonment with a mandatory minimum of 25 years.
