Best way of dealing with this would be to all bail up outside local nick with Press in tow. Insist on all soldiers giving DNA whether police want it or not - piss on the duty desk might be appropriate. Then ask then to put up or shut up with the briefing they give the journos. Piddle on a few of them as well while at it.
What a crock... the comments on the story by the locals sum it up well. Could be a soldier... my aching sack, it could be the reporter's brother or the mayor for all they know! Gotta love journalists who substitute their own twisted conjecture for actual reporting of the facts as known.
