An aficionado of the American Revolution and Civil War, Hall traveled around the Midwest for historical reenactments and is believed to have abducted, raped, tortured, and murdered dozens of girls and women.

However, authorities believe he could be responsible for the deaths and disappearances of between forty and fifty young women, which would place him among the most prolific serial killers in American history.

He spent his first few days in a neonatal intensive care unit due to lack of oxygen after his identical twin brother Gary "fed on him in the womb" in a monochorionic pregnancy.

Larry's father lost his job when his aggressive alcoholism caused him to put cadavers in the wrong gravesites, forcing the family to leave the house allocated for them in the cemetery and move to a shack with just one bedroom.

Over the subsequent decade, numerous female corpses, some young and unidentified, were discovered and later attributed to Hall due to their bodies being strangled and sexually mutilated.

He abducted his victims, who were primarily but not exclusively young white girls and adult women, and would often, but not always, rape and torture them, and then stab or strangle them to death.
