10 Serial Killer Crimes That Took Years To Solve

The Wests are possibly one of the most famous duos when it comes to serial killers. The English couple committed at least 12 murders during the 20 years they were at large.

Whilst an adolescent Fred impregnated his sister and admitted to molesting many young girls, his family effectively disowned him, however, he remained in touch with is parents. During his first marriage to Rena, Fred was constantly violent and controlling. This extended to sexually assaulting Rena's daughter Charmaine, the abuse continuing for years. Rena eventually escaped but left her daughter under the care of Fred and their nanny McFall. McFall later disappeared but was never reported missing.

In 1969, Fred met Rose and the pair began their relationship despite the protests of her parents. Rose quickly began beating the two daughters and is believed to have killed Charmaine. Rena sporadically returned to visit the children but after one visit was never seen alive again. The infamous pair got married and had children of their own who were also subject to excessive abuse.

They murdered and assaulted many people but eventually turned their attention to daughter Heather who they killed and "buried under the patio". This would prove to be their downfall as the family joke of ending up like Heather garnered attention from the police.

The police mounted a full investigation after their daughter Louise opened up about the abuse. The pair we eventually arrested in 1994 for the murders and abuse on multiple counts. Fred strangled himself in prison a year after his arrest.
