U.K. police: ‘High dose’ in Novichok death of woman

LONDON — British police said Monday they believe the latest victims of poisoning by a nerve agent must have handled the material’s container and been subjected to a “high dose” of the lethal poison.

Metropolitan Police Assistant Commissioner Neil Basu said the death of 44-year-old Dawn Sturgess on Sunday shows that she and partner Charlie Rowley, 45, were exposed to a large quantity of Novichok, a military-grade nerve agent produced in the Soviet Union during the Cold War.

Basu said the working theory is that their exposure was linked to the earlier Novichok attack in March on ex-russian spy Sergei Skripal and his daughter Yulia, who have both survived despite extended hospitalizations.

Britain has blamed Russia for the poisonings, but Moscow has strongly denied any involvement.

The wide investigation is now a homicide inquiry. Basu expressed sorrow for the death of Sturgess, who had three children.

“Her death has only served to strengthen the resolve of the investigations team,” he said, saying the immediate police priority is to find any container that may be the source of the Novichok.

He said no one else in the Amesbury and Salisbury region where the couple lived in southwestern England has shown any sign of Novichok poisoning.

More than 100 police are working to search all areas where Sturgess and Rowley had been before they became ill nine days ago. The search is focused on their homes and a park in Salisbury.

Rowley remains in critical condition in a Salisbury hospital.
