Perhaps.
Slain British politician Jo Cox was the victim of an "isolated, but targeted attack," West Yorkshire police said Friday.
A local official briefed by police told CNN that the gunman "lay in wait" for Cox.
A 77-year-old man who intervened to help Cox also "sustained a serious injury," police said. He's stable but remains in the hospital.
The killing has muted the tone of public discussions over the referendum, which has focused heavily on immigration. It put the brakes on official campaigning, with both sides suspending activities out of respect for Cox, just as they had begun to ratchet up their arguments in the final leg of the race. The BBC canceled a TV debate on the referendum scheduled for Friday night.
The pro-Brexit campaign called off major events for Saturday, including a big rally planned in Birmingham, Robert Oxley, a spokesman for Vote Leave, told CNN.
