It was a happy photograph, a snapshot of a moment in an at times heated, but thoroughly English, debate on the EU. Less than 24 hours later, the MP, a former aid worker, politician and mother of two small children, was dead and everything had changed..
As details of the attack on the MP filtered through the news wires, through social media and on the television, the extreme violence and sustained nature of the assault became clear.
It was shortly before 12.53pm Thursday. Inside the one storey red-brick library, in Market Street in Birstall, West Yorkshire, Cox had been listening to her constituents, members of the public who had voted her into parliament only a year ago.
She emerged, flanked by two personal assistants, to head to a meeting for the EU #remain campaign. It was a busy day in her constituency. At the same time customers clutching their lunch came out of Sandwich & Co and the sound of popping, like a balloon bursting, caused many to turn their heads.
In the aftermath of the jocular battle of the #Thames, #Jo Cox tweeted a picture of her family in a dinghy flying the “in” flag for Europe. “My hubby @MrBrendanCox & children taking part in the battle of the Thames – because we’re #StrongerIn Remain.”
