Earlier this week, the former spokesman for ex-Liberian President Charles Taylor's rebel National Patriotic Front of Liberia (NPFL) movement was found guilty of immigration fraud in the US for lying about his role in his country's civil war.
Tom Woewiyu’s conviction comes months after the Liberian warlord known as "Jungle Jabbah" was sentenced to 30 years in prison in the US for falsely saying he had never belonged to an armed group.
Around 250,000 people were killed in Liberia's brutal 14-year civil war.
Elizabeth Blunt, who reported on the civil war from Liberia in 1990, has written a blog about how she testified in Woewiyu’s trial in Philadelphia:
I am not good at throwing things away, and my files, containing all the written reports I did as the BBC's West Africa correspondent, are now a very useful resource for anyone attempting to establish what happened when."
She said that Woewiyu, now 73, had been "a good choice for a PR man, a fancy dresser and a great talker, with just a whiff of the used car salesman”.
The former BBC reporter said most of her evidence was straightforward:
Woewiyu had claimed during the naturalisation process that he had never been a member of any political group and had never advocated the overthrow of any government.
I could testify that he was heard regularly on the BBC speaking on behalf of the NPFL, calling for the then-President of Liberia, Samuel Doe, to get out, and threatening to go all the way to Monrovia and get rid of him, if he didn't go of his own accord.
And also that when the BBC named an interviewee, they were pretty well always who the BBC said they were."

Woewiyu is due to be sentenced in October.
