I assume you have looked him up in the on-line catalogue of the National Records of Scotland. They have reference to a precognition in 1829 (ref. AD14/29) in connection with theft at Peacock's Close, Aberdeen.
However, when you read the account of the trial in the Aberdeen Journal of 22-4-1829, the procurator fiscal did not bring that charge. Instead James and his accomplices admitted being regular thieves and in particular the theft (on 3-9-1828) of money, clothes and jewellery (which is described) from the house of Dr Brown, Principal of Marischal College.
