Sean Vincent Gillis: The Other Baton Rouge Serial Killer

Early Life

Sean Vincent Gillis was born on June 24, 1962, in Baton Rouge, Louisiana. Raised primarily by his mother after his father abandoned the family, Gillis had a seemingly ordinary upbringing. However, beneath this facade lay dark obsessions that would later manifest in his gruesome crimes.

The Crimes

Over a decade, from 1994 to 2004, Gillis embarked on a series of brutal murders, targeting women in the Baton Rouge area. His modus operandi often involved abduction, rape, and murder, followed by acts of necrophilia, mutilation, and even cannibalism.

  • January 4, 1999: Katherine Ann Hall, 29 Hall's body was discovered mutilated and posed in a manner suggesting Gillis's escalating brutality.
