The woman killed was Myra McKee, a young, well respected Irish journalist standing with a group of ?journalists beside a police landrover.

Although claimed to have been an "accidental killing" and that shots were allegedly fired at the police, is it possible there is more to this story?
From the released footage the masked shooter seems to be taking careful aim, and a colleague appears to pick up the used shell casings.
( As far as I can find no other shots were fired that night.)

Lyra McKee had signed a book deal with Faber:
"Her first book – Angels with Blue Faces – is due out this year, and deals with a cold case murder of a Northern Ireland MP during the height of the Troubles.
…Her second book The Lost Boys was due to be published next year.
The book explores the disappearances of a number of children and young men during The Troubles. From the publisher’s blurb:
Many of them were not believed to be victims of the IRA or the UVF. Some were kids who left home for school and never came home and their disappearances were never solved by the police.
McKee will investigate what happened to them."
Looks like her investigation and her "The Lost Boys" book will never happen now.
PS Time line is interesting:
Pelosi delegation arrives in Ireland April 16th,
Lyra McKee killed April 18th,
Pelosi expressed her condolences to her family. April 19th.
