Chris Hurst, boyfriend and co-worker of Alison Parker, one of the two TV journalists who were shot and killed live on air in Roanoke, Virginia, Wednesday morning, spoke to CNN Thursday about how he's coping with the tragedy and remembering Parker's life. Parker, along with her photojournalist co-worker Chris Ward, were murdered during a live broadcast by a former employee of the TV station they worked for.

Vester Lee Flanagan II, who went by the pseudonym Bryce Williams, was a former reporter for the WDBJ7 news team based out of Roanoke. He was fired in 2013, amid reports that he was impossible to work with because of mood swings, and he grew more volatile in the years since, according to a manifesto he sent to NBC as a suicide note. Flanagan walked up to Parker, 24, and Ward, 27, Wednesday morning, who were in the middle of filming an outdoor segment for the morning news, and allegedly opened fire, killing them both and wounding a third person being interviewed on air. Flanagan died later that day from a self-inflicted gunshot wound, police said.

"I am trying to find the strength that she always said I had inside of me," Hurst told CNN's Chris Cuomo in an interview Thursday, adding, "It doesn't feel like I have it right now." Hurst, who is also an anchor for the station, said the pair had been dating for nine months and were very much in love.

In the emotional interview, Hurst spoke of the love they had shared and his sadness at "not being able to keep her safe." He also took to Twitter immediately after the shooting to describe how "radiant" Parker had been.

"The focus of this story should be two amazing lights that were extinguished yesterday for no good reason," said Hurst.
