While a formal identification has yet to take place, the Buckley family has been informed.
A 21 year old man arrested in connection with the disappearance of the Cork nurse is due in court tomorrow.
Overnight, Police Scotland issued a statement confirming the worst fears of many, that human remains had been discovered on a farm north of Glasgow.
The scene at High Craigton Farm was a hub of activity last night as emergency vehicles descended on the rural area, some 13 kilometres outside the city.
In a shift of focus from earlier search sites in Glasgow, two new areas were cordoned off.
Windyhill Golf Club and High Craigton Farm are near Milngavie where a grey car police were keen to trace had been spotted driving erratically on Monday.
Now police say they believe the body is that of Karen Buckley, who had been missing since Sunday morning.
Police will await the outcome of a post-mortem, but are following a definite line of inquiry.
They’ve arrested a 21 year old man, who is expected before a magistrate tomorrow, where he ll be formally charged.
Karen had been doing a Masters in Occupational therapy at Glasgow Caledonian University.
The University has issued a statement expressing its deep sadness, and is offering the close-knit student body counselling sessions.
