Colin Ross used a metal pipe and a rock to attack the woman
A judge has called for a further report on a 34-year-old man who pleaded guilty to trying to murder an American tourist near Inverness, leaving her in a coma.
Colin Ross used a metal pipe and a rock to attack schoolteacher Marty Layman-Mendonca, 57, on 5 July.
Lord Wheatley deferred sentence and adjourned the case to the High Court in Glasgow on 31 October.
The case had previously been deferred to the High Court in Paisley for a social inquiry report.
Deferring sentence once more, Lord Wheatley told Ross: "I intend to obtain a risk management report."
Earlier this month, the High Court in Glasgow heard the schoolteacher from Vermont was attacked on her third visit to Scotland.
The court heard how Ross, of Waterloo Place, Inverness, had set a trap for a female victim on the Great Glen Way.
Ms Layman-Mendonca was on her way back into the city when she was attacked.
Ross admitted attempting to murder his victim by repeatedly striking her on the head and body with a metal pipe and a boulder.
He also admitted carrying her into a wood, dumping her and stealing her possessions before tying her wrists together with shoelaces.
Ms Layman-Mendonca, a committed Christian, was dropped off by a friend at Blackfold at about 1130 BST on the day of the attack.
She said she could walk the last six miles of the Great Glen Way.
Ms Layman-Mendonca has been flown back to the US
Ross was walking in the same area and he told police that after their paths crossed he "became enraged" and decided to attack her.
The court heard how Ross, who attacked a female German tourist in 2004, followed his victim for 10 yards, engaged her in conversation and then "went into a frenzy".
He repeatedly hit her on the head with a metal pipe and a boulder before stealing the rucksack from her back and rifling through the pockets of her walking shorts for cash.
Ross then tied Ms Layman-Mendonca's wrists with shoelaces, leaving her unconscious and bleeding heavily.
The woman was found in a ditch beside the track by a police officer with a dog.
Ms Layman-Mendonca, who was receiving treatment at Raigmore Hospital in Inverness, has returned to the US.
