Police do not know whether fugitive speedboat killer Jack Shepherd has fled the country, it has emerged.
Detectives do not have a database of who has left the country and do not have the resources of a counter-terrorism operation, Scotland Yard said.
Shepherd, 31, was convicted of manslaughter in his absence after his speedboat flipped over in the Thames and his 24-year-old date Charlotte Brown drowned.

A police spokesperson told the Sunday Telegraph: ‘We have no idea if he is in the country or not … we cannot be certain.
‘If there were more officers on the case, we might be able to do something. If this was a counter-terrorism operation, we might be able to do something.’
The case was harder than usual because of the time frame of ‘many months’ and because it was not known where Shepherd might have left from, they said.
Earlier this month police there was ‘no tangible trace’ of Shepherd since he last appeared in court.
His passport was not seized as he had complied with bail conditions before his disappearance last year, police said.
Ministers have led the calls for Shepherd to have legal aid cut off until he returns to face justice.

Sajid Javid called the situation ‘heart-breaking’, saying: ‘Her parents have suffered enough and Mr Shepherd should give himself up right away.’
Web designer Shepherd, 30, had been trying to impress Ms Brown after meeting her on dating website OkCupid.
They took champagne aboard the speedboat for a trip past the Palace of Westminster on their date in 2015.
In mobile phone footage, Ms Brown could be heard shouting that they were going ‘so fast’ as Shepherd drove at more than double the 12 knot speed limit.
The boat capsized near Wandsworth Bridge in central London when it hit a submerged log after a drunken Shepherd encouraged his date to take the wheel.
They were both thrown into the cold water and Ms Brown died after she was pulled from the river unconscious and unresponsive.
