The two journalists killed during a live TV report were both shot in the head.
Reporter Alison Parker, 24, and cameraman Adam Ward, 27, died of gunshot wounds to the head and body, a Virginia coroner said.
Their former colleague Vester Flanagan shot himself when police caught up with him three hours from the scene of the killings.
The boyfriend of shooting victim Alison Parker said he hopes other people get to experience the love he shared with her "at least once in their lives".
Chris Hurst, who worked with Alison at WDJB7 News, said the pair who had been dating nine months had not yet revealed their relationship to colleagues.
He told reporters: "I believe she would want our love to be shared because it was a love that was genuine.
"It was a love that I hope everyone gets to experience at least once in their life."
Vicki Gardner, who was being interviewed live on-air when a gunmen shot two journalists has been released from hospital.
In a 23-page fax, Vester Flanagan said he was a "human powder keg waiting to go boom" before he slayed Alison Parker and Adam Ward.
Police confirmed Vester Flanagan shot himself hours after killing two former colleagues Alison Parker and Adam Ward on live TV.
