The detective who snared Scotland’s most notorious serial killer believes he will never reveal the true number of lives he took.

David Swindle fears evil Peter Tobin - who is suspected of a string of other brutal murders all across the UK - will take his secrets to the grave.

Tobin's health is deteriorating in hospital as he is ravaged by cancer, while he has also suffered a broken hip.

Despite knowing his time is running out, he has continued to ignore desperate pleas by victims’ families to come clean about the true catalogue of crimes he has committed.

The 76-year-old is serving life for the murders of Angelika Kluk, Vicky Hamilton and Dinah McNicol.

Mr Swindle, who led Operation Anagram which delved into Tobin’s crimes, told the Glasgow Times: “We know he’s responsible for other murders, but we just need the evidence.

“He only cares about himself and is incapable of thinking of others. Much like child killer Ian Brady, who went to his grave without revealing where he buried his last victims, Tobin is likely to do the same. It’s all about the power and control he thinks it gives him.

“He will die, and my hope is he finally finds a crumb of decency to tell the families of those he killed what he did and reveal what he did with their bodies, but I doubt Tobin is capable of thinking of anyone apart from himself.

“He’s never showed any remorse for his crimes, not an ounce. He’s only interested in himself and doesn’t care about his victims or the heartbreak he’s caused.”

Tobin’s crimes finally came to light after he was convicted of the brutal killing of Angelika, 23, who was bludgeoned to death and stabbed 16 times.

Her blood-soaked body was dumped through a hatch in the chapel floorboards at St Patrick's Roman Catholic Church in Glasgow city centre. She was hidden next to the confessional box, with her hands bound and mouth gagged.

She befriended Tobin, who was working as a handyman at the church after being released from jail for sexually assaulting two 14-year-old girls.

But unbeknown to Angelika, the remains of two teens who vanished in 1991 were buried in the garden of his former home in Margate, Kent.

Five days later, Mr Swindle, who at that time was a detective superintendent with Strathclyde Police, visited the church where Angelika's body had been discovered, sparking his connection to the serial killer that has lasted to this day.

Mr Swindle worked on hundreds of murders and complex high-profile UK-wide investigations during his 34 years in the police, including his management of the Glasgow Airport terror attack.

He went on to set up David Swindle Crime Solutions and Victims Abroad, supporting families whose loved ones are killed abroad as a result of homicide or in suspicious unexplained circumstances.

Now he will be giving a series of talks across Scotland sharing his expertise and discussing prolific cases he worked on.

His Catching Killers tour is coming to Oran Mor in Glasgow’s West End on December 6.

Glasgow Times:

He added: “I’ll be discussing some of the high-profile cases I’ve worked on, including Tobin and many more.

"It’s an opportunity for people to get a real insight into police work and find out more about the investigations and techniques used to catch murderers.

“Serial killers are cunning, conniving, controlling, careful, and I hate to say clever individuals who live apparently normal lives and get away with their crimes for years until eventually detected.”
