British counter-terrorism police said on Friday they believed they had found the source of the Novichok nerve agent that killed Dawn Sturgess in southwest England this month and left her partner Charlie Rowley critically ill in hospital.
"On Wednesday, 11 July, a small bottle was recovered during searches of Charlie Rowley’s house in Amesbury," police said in a statement. "Scientists have now confirmed to us that the substance contained within the bottle is Novichok."
