What the papers say
Journalist Mike Philpott takes a look at what's happening in Wednesday's morning newspapers.
In the Telegraph, a neighbour describes it as being like a "scene from a horror movie".
He tells how a woman who was also stabbed in the incident turned up at his door "covered in blood and screaming that a man was dead in her kitchen".
The Irish News and the The Mirror both report that a supermarket worker who was sacked in a dispute over the loyalist song The Sash has served time in prison for the murder of two Catholic brothers 35 years ago.
The Irish News says William Charles Hunter was reinstated after a loyalist protest at the Asda store on Belfast's Shore Road. But it later emerged that he shot Thomas and John McErlane after luring them to a card game in the Mount Vernon estate in 1975.
The The News Letter leads with a report that hardline Orangemen have criticised colleagues in Coleraine for accepting lottery funding for a festival on the Twelfth.
Political matters are high on the agenda in Dublin.
The The Irish Times reports that the Labour leader in the Republic, Eamon Gilmore, has ruled out a coalition with Fianna Fail after the next election, even if he were in a position to become taoiseach.
In a wide-ranging interview with the paper, Mr Gilmore says twice that a coalition between his party and Fine Gael would be the most likely outcome after the country goes to the polls.
But Fine Gael makes its own headlines. The Irish Independent reports on its front page that rifts within the party have been re-opened in what it calls "spectacular fashion" after a TD criticised the party leader, Enda Kenny.
The paper says Mr Kenny is "seething" after Lucinda Creighton attacked him for organising a golf fundraiser which led to a donation from a leading property developer. She tells the paper that the donation should be handed back.
David Cameron's meeting with President Obama is a major talking point almost everywhere.
Pictures of the two men appear in almost every paper.
In the Irish Times, their discussion in the Oval Office is overseen by a portrait of Abraham Lincoln.
In the The Daily Telegraph, it's George Washington who's looking down from the wall above them.
The The Guardian reports on one of their main topics of conversation - the release of the Lockerbie bomber. The paper says Mr Cameron resisted demands for an inquiry, but he agreed to release some of the files about the case.
The Daily Mail says they also discussed the case of Gary McKinnon, the man with Asperger's Syndrome who's the subject of an extradition request for hacking into Pentagon computers.
The paper says Mr Cameron's intervention resulted in the first softening of the US approach to the case.
The meeting provides fertile ground for the cartoonists.
Some of them have quite serious points to make, albeit with a touch of humour.
Matt in the Daily Telegraph wonders if Mr Cameron's assertive approach means the end of the special relationship. It shows him telling Mr Obama: "I think we should both start seeing other countries".
