The gunman who shot dead two US TV journalists live on air filmed himself carrying out the killings.
Footage posted on the Facebook account of Bryce Williams- another name used by Vester Lee Flanagan - shows the gunman walking up to where Alison Parker and Adam Ward are filming a live interview.
As he gets closer towards them, a hand is seen lifting a gun and pointing it directly at Alison.
The video stops at this point but a second video, which ITV News have decided not to post, shows the shooting itself.
A number of shots are then fired and Alison screams and runs out of view.
The 24-year-old WDBJ7 reporter and cameraman Adam Ward, 27, were later revealed to have died.
This video shows the moments leading up to the shooting.
The Facebook and Twitter accounts of Bryce Williams have since been taken down.
