A “parasitic” fraudster has been found guilty of killing a vulnerable older woman and hiding her body in a graveyard in a plot to plunder her money.

Serkan Kaygusuz, 42, conned and cajoled 70-year-old Norma Girolami out of her wealth after flirting with her in the hot tub of swimming baths in Archway in 2017.

While their sexual relationship was short-lived, he went on to make increasing demands for cash totalling some £300,000.


It is understood the defendant, who claimed unemployment benefits and lived with his parents, spent the money on a luxury lifestyle well beyond his means.

He had a £20,000 car, bought designer clothes, a new games console and went on a trip to Turkey for a hair transplant while hoarding around £120,000 in the bank.

When Norma stopped paying in May 2021, he plotted to take what remained of her assets by killing her, the Old Bailey was told.

At the time, she had been affected by the death of her father and her funds were rapidly dwindling, jurors heard.

Prosecutor Jocelyn Ledward said: “By August, the defendant must have realised that his comfortable parasitic lifestyle was not going to continue: he was simply not going to get any more out of Ms Girolami. At least not whilst she was alive.”

Before carrying out the murder, the defendant made a series of “sinister searches” online for garden tools, caustic soda, hydrochloric acid, “deed for property transfer” and “will and testament”.

He also bought rope, a “soft ball full mesh mouth plug with adjustable belt” which can be used to restrain a person, handcuffs, gloves, plastic overalls, tape and a spading fork tool on Amazon.

On August 19 2021, Ms Girolami travelled from her home in Highgate for a day out at Leigh-on-Sea in Essex.

Upon her return, the defendant went to her flat and killed her.

Kaygusuz pretended to her friends that she was alive and well while systematically draining her bank accounts and applying for loans of £60,000 in her name.

Some 15 months after she went missing, Norma’s remains were found hidden “in plain sight” in a grave in St James’s Churchyard in Barnet.

A post-mortem examination found she had suffered blunt force injuries to the chest, rib fractures and bruising consistent with “third party assault” although the cause of death was “unascertained”.

As the net closed on Kaygusuz, he changed his name to Sean Kaya and began looking to go to Canada for a new life.

The defendant, who declined to give evidence, admitted taking her money and items of jewellery which were recovered from his girlfriend’s home.

He also pleaded guilty to perverting the course of justice by concealing and burying her body but denied murder.

But divorcee Kaygusuz, of Sparsholt Road, Crouch End, was found guilty of her murder today (February 21).

The jury was not told the defendant – described by police as vain, greedy and arrogant – had a previous conviction of voyeurism for taking photographs of women at a swimming pool.

Kaygusuz gave no reaction as the jury delivered its guilty verdict.

He was remanded in custody to be sentenced on Wednesday (February 22).

The former supermarket worker will also be sentenced for perverting the course of justice; three charges of fraud relating to bank loans totalling £60,000 in Norma’s name and cash withdrawals; and transferring criminal property, which he had admitted.
