Florida

Danny Rolling earned the name the Gainesville Ripper after a four day rampage through student housing near the University of Florida in August 1990 left five young people dead. He mutilated and deliberately posed his victims, severing one woman's head and placing it to face anyone who walked into the room. Police initially chased the wrong man, a troubled student named Edward Humphrey, whose grandmother collapsed and died on her own doorstep while fending off a reporter during the hunt.

Rolling later claimed an alter personality called Gemini had driven him to kill, a story investigators quickly dismissed after learning he had watched a film featuring a killer of that exact name days earlier. He pleaded guilty before trial and was sentenced to death. On this day in 2006 he was executed by lethal injection at Florida State Prison, having eaten a last meal of lobster tail and sung a gospel hymn.

Shortly before his execution Rolling handed authorities a written confession admitting to an earlier unsolved triple murder in Shreveport, Louisiana, but made no final statement on the gurney itself.

Aileen Wuornos killed seven men in Florida, and later claimed the first death was self defence against a convicted rapist. By the time her case reached its final stage, she had turned against the very lawyers trying to save her.

When her appeal team moved for a retrial, Wuornos went to court and had them fired, insisting she was sane and wanted no further appeals. Many who studied her, including documentary maker Nick Broomfield, came to believe otherwise, pointing to erratic, unsettling behaviour in her final interviews as a sign of serious mental illness. The courts accepted her wishes regardless, and she was executed by lethal injection in 2002, declining a final meal.

Wuornos went to her death on this date maintaining a defiant, confused mix of guilt and conspiracy claims rather than a clear confession or denial.
