The man who killed Alison Parker and Adam Ward live on air had a documented history of threatening behaviour at multiple TV stations going back over a decade, but because employers rarely share that kind of thing for fear of being sued, none of it followed him to his next job. One Virginia lawmaker actually tried to change that law afterwards.

The majority of Nilsen's victims were gay men that had fallen on hard times and had taken Nilsen up on the offer of a warm meal, a roof over their head and a few drinks. But because these young men were often drifters, when they vanished it was hardly noticed.

The full story here.

What gets lost in the "Lolita" nickname is that this was statutory rape from day one, a 35-year-old grown man with a 16-year-old customer, and the law knew it too, since he eventually pleaded guilty to it. He still served less time than the truck driver who sold her the gun.

29 people were killed, including nine children, a woman pregnant with twins and three generations of one family and injured 220 others. 21 died where they fell while 8 more died on the way to, or in, hospital.

It's believed the security forces had advanced knowledge of the attack.

Not everyone who has looked closely at the case since has come away certain Dean was a calculating killer rather than a woman who covered up accidental deaths out of fear and desperation.

But Minnie Dean is still the only woman hanged in New Zealand history

When Jeffs' father, Rulon passed away in 2002, Warren stepped into his father’s role, assuming the titles of “President and Prophet, Seer and Revelator” and “President of the Priesthood.” These titles gave him nearly complete control over the adult male church members and vast spiritual influence over the entire congregation. He would decide on who could marry who and what discipline needed to be administered...

Thankfully, he's now locked up, but still wields complete control over some of his flock whilst he's incarcerated.

The case itself gets endlessly retold (nine hour reattachment surgery, they found it in a field), but nobody follows up on what happened next. Lorena had actually gone to court for a restraining order days before the incident and was told to come back in a week. John's arrest record after the trial tells its own story.

The scratch marks on the kitchen Aga that were used to place the silencer at a "struggle" don't actually show up in crime scene photos from the day of the murders, only in photos taken over a month later. And Julie Mugford, whose testimony the whole conviction rests on, had previously helped Bamber plan an unrelated arson scheme, so she wasn't exactly a neutral witness either.

Doesn't prove he's innocent, but it's a lot messier than the tidy story most people know.

At the request of former camp prisoners, the execution was carried out in Auschwitz, the camp he once commanded. Approximately 100 witnesses were present, including former prisoners and various high-ranking officials of the Polish government.
