The family of Lyra McKee have written to residents in Creggan in Londonderry appealing for information ahead of the second anniversary of her killing.
The family are asking local people to help them "achieve justice for Lyra".
Paul McIntyre, 52, from Ballymagowan Park in the city has been charged with her murder, which he denies.
At a previous court appearance the prosecution alleged Mr McIntyre was seen walking beside the gunman and that he was seen crouching down and picking up four cartridge cases from the gun used to murder Ms McKee.
