Two fraudsters who groomed a vulnerable elderly man and made him a tenant in his own home have been jailed after a four-year police inquiry.

John Paul O’Connor, 37, of Knatts Valley Road, Kent and Tony Casey, 34, of Barnet Road, Hertfordshire, pleaded guilty to conspiracy to defraud part way through their trial.

They were both jailed for eight years at Kingston Crown Court on Friday, February 7.

The pair were behind a complex conspiracy in which they groomed the victim to take over his home for a fraction of its value and eventually defraud him of more than £1.1 million.

Police became suspicious while investigating Casey for an unrelated matter and examined his bank accounts in late 2015.

A financial investigator noticed he had recently opened a new account and an unexplained cheque for £3,600 had been paid in.

In May 2016, Detective Constable Siobhan Cowlin attended a property in Brookwood Road, Wandsworth, in the hope of speaking to the man whose cheque was cashed.

She was told by a neighbour that he had died approximately six weeks earlier.

DC Cowlin then began to untangle a complex web of contact between the elderly man and O'Connor and Casey over more than 12 years.

The victim is believed to have first met the men when he had building work completed.

Bank statements showed unexplained large withdrawals between May and August 2003 of between £2,500 and £5,000. A total of £32,500 was taken out.

Neighbours said Casey or his associates would often take the victim to the bank.

In 2008 a relative of O’Connor bought the freehold for the extremely low value of £20,000. At that time the property was worth £500,000.

A few months later, Casey became the ‘landlord’ of the property in Brookwood Road.

Police discovered the victim's address had been up for sale for £949,000 since June 2015 with a sitting tenant.

After the victim died, Casey posed as the victim's nephew or grandson in order to deal with probate, meaning he would be entitled to take control of his assets.

He instructed the victim's solicitor to sell the Brookwood Road house and revoke a lease-for-life agreed with the victim as a sitting tenant.

In January 2017, a female relative contacted police after sending the victim a Christmas card that was returned to her and discovering his house was for sale.

She was shocked to discover the victim had died without her knowledge and that someone she had never heard of had arranged his funeral and was now the owner of his house.

Casey was interviewed at Sutton Police Station in September 2017 but when asked to prove he was the grandson or nephew of the victim, he refused and left.

DC Cowlin and her police colleagues continued to investigate and Casey was charged with fraud by false representation in August 2018.

O’Connor, whose support was integral to the complex fraud, was charged with the same offence in January 2019.

DC Cowlin said: “This was a truly horrible, calculated and predatory fraud investigation in which two men groomed and took full advantage of a vulnerable elderly man.

“Had it not been for a family member contacting the police, then Casey and O’Connor might very well have got away with this crime.

“Although this investigation has taken years to complete, it was worth it to see these two men behind bars.

"It would not have been possible to have secured this sentence without the continued dedication and hard work of the Met’s Financial Investigators, who supported me throughout.”
