Cases where you’re *convinced* a suspect has been wrongfully

Steven Truscott was wrongly convicted of killing his classmate, Lynn Harper, back in 1959 & was almost executed for it (he got a reprieve because of his young age).

He was acquitted in 2007, 48 years later.

Lindy Chamberlain, on a camping vacation with her family. The 3 children including their 3 month old Azaria are tucked into the tent while the adults are 20m away at a picnic table. Lindy hears something, rushes to the tent and sees a dingo taking away Azaria.

A few weeks later big city detectives smell a rat. The local barflys find out that the family are 7th Day Adventists, some sort of crazy cult, and "Azaria", some sort of weird name, means child sacrifice.

They get a fast talking professor from England who is certain tooth tears on a blanketare actually done by scissors, and his blood test detects blood all through the car and lindys husbands camerabag. She lied that Azaria had been wearing a jumpsuit.
Life for murder.

I had been living in Darwin and knew the locals were insular and knew nothing about the world. I also knew some 7th Day Adventists, who aren't crazy despite being vegetarian, and knew Lindy was gone.

Several years later Azarias jumpsuit was found in a dingos lair, and Lindy was released, eventually to be acquitted with a new coroners report stating Azaria was taken by a dingo.

Fuck a jury of your peers.

I was living in London in 1974.
Bombs went off in two Pubs in Guildford frequented by soldiers. Four people died.
A few weeks later a bomb in Woolwich killed 2 more people.
The Guildford 4 were convicted and the Macquire 7 (including the father of one of the Guildford 4) were convicted of handling the explosives used. 

At the time I said with the hatred Londoners had for the Irish, if St Patrick was arrested he would be convicted.

15 years later they were all released, except for Guiseppe Conlan, the father who had travelled to London to support his arrested son and who died in prison) because it was proved confessions were either fabricated by the police or extracted under torture.

At the same time two Pubs in Birmingham were bombed and the Birmingham 6 were arrested and convicted. 20 years later they were released due to tortured confessions and botched forensics.

In all those bombings others have either confessed or been named as responsible. So much for British justice and the jury system.

There's been an interesting, but I assume unsubstantiated, idea bruited about that Lindbergh himself might have arranged the infant's death; as a supposed endorser of the Aryan ideal of the perfect or 'master' race, it's thought that Lindbergh might have been severely upset over the possibility that his son was not physically perfect and might have suffered from some manner of mental and or physical defect:

I admit I've had some doubts as to whether Hauptmann was the actual criminal; it seems fairly certain that it would have been highly unlikely, if not actually impossible, for him to have received an impartial trial given the high public feeling and enormous negative pre-trial publicity surrounding him.

It's been substantiated that Disney was a willing FBI informant during the HUAC/McCarthy frenzy, and there's reliable evidence that Lindbergh had no problems with Nazi racial and eugenics policies. Although I'm quite ready to admit that not all leftists are admirable human beings, there's no point in denying that both of these men harbored a darker side to their public personas, although the claim that Lindbergh might have engineered the death of his own toddler son does seem going out there a bit.
