Few crime shows are as impressive as "Fargo". So when the show's season 2 premieres this fall, we wonder what crime story will unfold. So far, the full cast for season 2 has been revealed; the cast from season 1 will not return and the new season's plot is centered on Sioux Falls murders, which took place in 1979.

"A lot of that has to do with the way the story unfolds, because truth is stranger than fiction. The goal for me is not to find a real life case and follow it. It's to create a fictional case that ends up feeling real," Sioux City Journal quoted Noah Hawley as saying. 

The "real life case" Hallway mentions refers to the Sioux Falls murders. While season 2 of "Fargo" will not go into the details of the murder case as pointed out earlier, it will most definitely involve the criminals as characters in the show. In the murders which took place on 17 November, 1979, three brothers, Allen Fryer (29), David Fryer (24) and James Fryer (21) were convicted and given life imprisonment without parole.

So who are the Fryers and what did they do?

Little is known about the Fryer brothers apart from the fact that they were known to create ruckus in the area. Their conviction, though, rests on the murder of four boys and the rape of one girl. The incident took place in Gitchie Manitou State Preserve, Iowa.

The Fryer brothers were deer hunting at the park when they heard their victims sing. David Fryer, who was sent to spy on them, came back saying that a group of four boys and a girl were having a campfire and had marijuana on them. Their victims were Roger Essem (17), Stewart Baade (18), Dana Baade (14), Michael Hadrath (15) and Sandra Cheskey (13) from Sioux Falls, South Dakota.

The brothers posed as policemen and shot the four boys. Sandra, the only girl in the group survived the attack. She was taken to a farmhouse in a truck by Allen Fryer and was raped by his brother, James.

On 29 November, Sandra was accompanied by Sherriff Craig Vincent and she identified the farmhouse and saw Allen drive the same truck. He was then arrested by law enforcement.

During their trial, the brothers famously said that they were under the impression that narcotic agents had the liberty to kill drug users indiscriminately.

The three brothers are still serving their sentence at Iowa State Penitentiary in Fort Madison, Iowa.
