Who Is Darlene Horton? American London Russell Square Stabbing Victim Was Visiting British Capital With Husband

The lone person killed during Wednesday night's mass stabbing in London's Russell Square has been identified as Darlene Horton, according to a Florida NBC news affiliate WJHG. Her name was announced by Thursday afternoon as more information emerged surrounding the attack for which authorities still have not decidedly ruled out terrorism as the cause.

Horton, who is from Florida, was among six people stabbed during the incident, but five others survived after sustaining various injuries. While the names of the other victims were not immediately released, their nationalities have been confirmed by London's Metropolitan Police force. The other victims are from Australia, Israel and Britain.

The 64-year-old woman was in London with her husband, Richard Wagner, a Florida State University psychology professor who was teaching a summer course at the college's London Study Program, according to WJHG.

“There are no words to express our heartache over this terrible tragedy,” said Florida State University President John Thrasher. “We are shocked that such senseless violence has touched our own FSU family, and we will do all we can to assist Professor Wagner and his loved ones, as well as his friends and colleagues in the Psychology department, as they mourn.”

The stabbing suspect has been identified as Zakaria Bulhan, according to local law enforcement. Before identifying him, London police announced the suspect as being "a Norwegian national of Somali ancestry." Police announced there was no "evidence of radicalisation or that the man was motivated by terrorism."

The mayor of London was also quick to be careful to assign motivation for the attack. "I have spoken with the Commissioner, and the Assistant Commissioner, who have assured me that our police officers are working extremely hard to investigate exactly what has happened and to keep the rest of us safe," Mayor Sadiq Khan said in a statement. "A man was arrested at the scene. Police have spoken to him and are seeking to establish the full facts including motives for this attack."
