A boy accused of abducting, raping and murdering six-year-old Alesha MacPhail is blaming a woman for the crime.

The 16-year-old went on trial charged with killing the child on the Isle of Bute in July last year.

The teenager, who cannot be named for legal reasons, pleaded not guilty at the High Court in Glasgow.

His legal team, lead by QC Brian McConnachie, have lodged a special defence on his behalf.

It is claimed the crime was committed not by him but by a woman named Toni Louise McLachlan.

Prosecutors allege the boy was armed with a knife when he took Alesha from her bed at a house in Ardbeg Road in Rothesay, Bute.

It is claimed the boy then carried the schoolgirl to the site of the former Kyles Hydropathic Hotel on the island.

The indictment states he took off Alesha's clothes, shook her violently before placing his hands over her nose, mouth and around her neck.

The boy is said to have "applied pressure" to her face, inflicted injuries by "means unknown" with prosecutors alleging he went on to rape and murder Alesha.

The teenager then faces a separate charge of attempting to defeat the ends of justice.

It is alleged he went to another house in Ardbeg Road before disposing of the clothes he had worn and then taking a shower to remove blood from his body.

This is said to have been done in a bid to "destroy or conceal evidence".

No evidence was heard on Monday.

Prosecutor Iain McSporran QC instead read out evidence agreed between the Crown and the boy's lawyers.

Jurors were told Alesha's body was found by a man at 8.54am on July 2 in the grounds of the former Kyles Hydropathic Hotel.

The child was pronounced dead around 30 minutes later at 9.23am.

Mr McSporran: "She had been murdered. Following a post-mortem examination of her remains, the cause of death was established as 'pressure to neck and face'."

The court also heard it was Alesha's gran, Angela King, who had reported the girl missing at 6.23am on July 2.

Lord Matthews told jurors the case is likely to "arouse strong emotion" but that they were to adopt a "professional detachment" to the evidence.

The trial continues.
