This week, Bill MacDowell starts a life sentence for the double murders of Renee and Andrew MacRae.
The case is 46 years old this year. Many people despaired of there ever being a result.
But at the High Court in Inverness on Thursday, after a long trial, a jury decided MacDowell should finally face what he did.
The 80-year-old will die in prison.
But what of the north and north east’s other unsolved murders and unexplained deaths? Does this change things for them?
We take a look at some of the most notorious cases – and their current status – here.
Alistair Wilson, Nairn
Young father-of-two Alistair Wilson was shot dead on his own doorstep on November 28, 2004.
The Nairn banker, 30 at the time of his death, went to the door after a man with a mysterious blue envelope asked for him by name.
Since then, police have explored theory after theory – was there a financial motive? Was it something in his personal life?
But to date, almost 18 years on, there have been no real answers.
Watch our documentary to catch up with the story.
George Murdoch, Aberdeen
George “Dod” Murdoch picked up his last fare in Aberdeen on September 29, 1983.
The 58-year-old was killed on Pitfodels Station Road. He was garrotted with a cheese wire.
Police began a hunt for the so-called Cheese Wire Killer – and a £25,000 reward for information is still on offer.
Dorothy Park, New Pitsligo
Almost as old as the Renee and Andrew MacRae case is the mystery of New Pitsligo postmistress Dorothy Park.
She was left for dead in what looked to be a bungled robbery in June 1981.
There was a theory that it was a copycat case after the reign of terror of Black Panther Donald Neilson.
He carried out a series of raids and assaults in England in the years prior to Dorothy’s death.
Sandy Ingram, Newmachar
Sandy Ingram went out to look for intruders on his Newmachar farm on June 19, 2010.
When he didn’t come back in, his wife Ann went to look for the 79-year-old.
She found him lying injured.
He underwent brain surgery, but died almost exactly a year later.
Police launched a major investigation and appeal for information.
They searched for a red Vauxhall car, and revealed bathroom and kitchen taps had gone missing from his farm prior to him being injured.
Detectives made a fresh appeal seven years after the tragedy, but there are still no answers.
On the 10th anniversary, we revisited the story.
Elizabeth Sutherland, Culbokie
Elizabeth Sutherland was a housewife from the Highland village of Culbokie.
Standing at 4ft 9in and just 6st 4lb, she was known as Totsie to her friends and family.
On Monday, September 24, 1984, the 30-year-old mother-of-two was brutally murdered in her Black Isle home.
She had been strangled and stabbed seven times and her throat had been slit.
The horror of the scene was compounded by the fact she was found by her 10-year-old daughter Jane.
George MacPhee, 50, was later jailed for life for the crime.
But in 2005, Mr MacPhee was released after appeal judges found his trial had been flawed.
To this day, no-one else has been charged with the murder.
