From an inconspicuous upbringing in a Co Down town to becoming the most wanted female terror suspect in the world.
The wife of one of the London suicide bombers, mother-of-three Samantha Lewthwaite, is on the run accused of spearheading a Muslim extremist group's jihad.
Dubbed the White Widow, Lewthwaite is wanted in connection with an atrocity in Kenya, her alleged role in bomb-making factories and terrorist activity in Yemen.
Such is the perceived threat posed by Lewthwaite, a dedicated unit of the elite SAS has reportedly been tasked with finding her.
While Northern Ireland is no stranger to homegrown terrorism, Samantha Lewthwaite's story is unique.
Born to a British soldier from England and a Northern Irish Catholic mother, Lewthwaite spent her early years in the family's home in Banbridge's Whyte Acres estate.
The family moved to Aylesbury in Buckinghamshire but in 1995 Lewthwaite's parents Andy and Christine separated.
Distraught, Lewthwaite spent more time with Muslim neighbours and was apparently drawn to the faith by their close family ties. Then, at the age of 17, she converted to Islam, marking her religious conversion by changing her name to Sherafiya and swapping jeans and jewellery for a traditional long gown.
In 2002, she married Jermaine Lindsay in an Islamic ceremony at a house in Aylesbury.
The pair met on an Islamic chatroom while she was studying religion and politics in London and he was working as a carpenter. Neither of her parents attended the wedding.
Days after her husband blew himself up on a London Underground train in July 2005, killing 26 people, pregnant Lewthwaite tried to distance herself from the attacks. She described the terrorist bombings as "abhorrent".
In a statement she explained: "Jamal is accountable for his actions 100% and I condemn with all my heart what he has done."
In 2009, Lewthwaite and her children disappeared from the UK.
She resurfaced two years later after travelling to Kenya using a false passport.
The Kenyan authorities issued a photograph of a woman wanted for questioning after a bomb factory was discovered at a house in Mombasa. The picture on it was that of Lewthwaite.
Police said they were tipped off that terrorists were planning a bombing campaign on shopping centres and hotels. Last year, Kenyan police revealed they were searching for her on suspicion of taking part in a grenade attack on a bar which had been packed with tourists watching an England football match. Three people were killed and 25 injured.
Lewthwaite is believed to be in the inner circle of al-Shabaab, an al-Qaida-linked group, the name of which translates as 'the people'.
It is understood she controls the group's finances and is a vital conduit between al-Qaida groups in Pakistan and east Africa.
Al-Shabaab is a militant group fighting to create an Islamic state in Somalia.
