The Engineer on the Rig

Updated 5 October 2026 by Investigation Bureau

An illustrative case story. It is a composite built from the kind of work our investigators have handled over the years. Names, places, dates and identifying details have been changed or merged so that nobody can be identified. The methods and the ethics are as described.

The enquiry did not come from the victim. It came from her daughter, which is how romance fraud usually reaches an investigator. The victim is the last person to ask for help, because the victim is in love.

Her mother, widowed for four years, had met "Callum" on a dating app. He was a pipeline engineer from the Highlands, 61 years old, on a long contract aboard a rig in the Gulf of Mexico. Seven months of daily messages followed: good-morning texts, voice notes in a soft Inverness accent, a hamper delivered at Christmas. In those seven months he had never once managed a video call. The rig's bandwidth was to blame, he said, and the time difference, and on one occasion a broken camera, for which he apologised at touching length.

She had sent him £5,600 in two payments. The first was a customs fee to release replacement tools. The second was a hospital bill after an accident on the rig. Her daughter found out when her mother asked about raising money against the house. What prompted the enquiry was the next stage. Callum had started to talk about the end of his contract, about coming home to her, and about a "transfer agent" who needed £54,000 in fees before his final settlement of £1.1 million could be released. That money, he promised, would be theirs.

The investigation

The daughter asked for one thing, which was proof her mother could not argue away. Everything else had been argued away already. She wanted it delivered gently, and she was right. An accusation without evidence only makes the scammer the one person who has "always believed in her".

We treated it as we would any fraud: preserve the evidence first, verify second. It was a cyber investigation from start to finish. Every profile, message thread and voice note was captured to an evidential standard, with tools we built and run ourselves, before anyone challenged anything. Scammers delete quickly once they are questioned.

Verification took five days. The profile photographs traced to a real man: a retired engineer in another country altogether, whose public pictures have been lifted for a great many fake profiles. That theft of a stranger's face is one of the sad constants of this crime. The metadata on those photographs placed them somewhere no rig could have been. The accent in the voice notes was consistent with the voice-generation tools these operations now use as standard. The website of the "transfer agent" had existed for nine weeks, its company number belonged to a dissolved shelf company, and its payment details led to a UK money-mule account. There was no Callum. There was a workflow, probably a rota of operators working many women at once from a single script.

The hard part

Evidence alone does not break the spell. It has to be delivered with care. We prepared a short, factual report written for her and not for a court, although a court-ready version existed as well, and went through it with her on a video call, her daughter beside her. What finally reached her was neither the photographs nor the shelf company. It was seeing the same "customs fee" script, word for word, in a post on a fraud-warning forum from two years earlier. The same sentences, sent to other women. After that she stopped arguing.

The real result of the case was that the £54,000 stayed in her account. Of the £5,600 already sent, her bank recovered part under the reimbursement rules for authorised push-payment fraud, once we had supplied the evidence pack. The rest was reported to Report Fraud (the national reporting service that replaced Action Fraud) with the full file. We are always honest about recovery. Once money has passed through a mule account it has usually gone for good, and anybody who guarantees to get it back is running the second act of the same fraud.

At the end she asked whether she had been stupid. She had not. Professionals had picked her out, as they pick out clever, kind people every day of the week. What they exploit is warmth, and warmth is no cause for shame.
