A-level girl accused of stabbing boyfriend to death 'had been on all-day drinking session'
A teenager arrested on suspicion of killing her boyfriend had been on an all-day drinking session to celebrate her A-level results the night he died.
Kat McGrath, 18, was questioned by police investigating the murder of Alyn Thomas on Sunday.
Friends and family of the 22-year-old, who was found in a pool of blood at McGrath's home, said he was devoted to her to the 'point of obsession'.
On her pages on a social networking website, Mr Thomas had written 'I love you' 12 times.
McGrath's parents are believed to have visited her in custody and are said to be devastated.
One of her friends said: 'Kat can be a bit fiery at times but we can't believe what has happened. Alyn was devoted to her almost to the point of obsession at times.
'But we can't believe he would have hurt her because he loved her too much.
'Everyone had been celebrating the A-level results or drowning their sorrows.
'It is just terrible that what should have been one of the happiest times of Kat's life has ended like this.'
Another friend said: 'Alyn loved Kat to bits, although some people thought it was a bit intense. She's a few years younger but he was very serious about her.'
Friends said the couple, from Bridgend, South Wales, had been together for more than a year.
On Sunday police found a knife that they believe is the murder weapon.
Mr Thomas was on a gap year from college working part-time in Tesco while McGrath was doing her A-levels at the town's Brynteg Comprehensive.
It is thought both were hoping to go to university after McGrath achieved passes in English, history and geography with two B grades and a D.
She had picked up her results just before 11am on Thursday before ringing her parents with the news. She then went into Bridgend with some of her fellow students to celebrate.
Some of the group went on to a house party later - with McGrath not meeting up with Mr Thomas until later in the evening.
He was found with knife wounds at her family's £400,000 home in Brackla, Bridgend, in the early hours of Friday morning. He was pronounced dead on arrival at hospital.
McGrath's father Martin, a businessman, had been at the family's holiday home on the west coast of Ireland, where his wife and daughter were due to join him.
He has since returned to South Wales where the family house has been sealed off by police.
Mr Thomas's family were being comforted by friends at their home on Sunday.
