Watch: Alexander Pacteau being interviewed by police during Karen Buckley murder probe
Police also release photographs
Police in Scotland have released footage from inside an interview room in relation to their investigation into the murder of Irish nursing student Karen Buckley.
Today, Alexander Pacteau (21) who was charged with her murder submitted a guilty plea at a Glasgow court hearing.
Karen, from Mourneabbey in north Cork, went missing following a night out with her housemates at Sanctuary nightclub in Glasgow in the early hours of April 12.
Her friends raised the alarm when the 24-year-old failed to return to the group in the nightclub after telling them she was going to the bathroom and would be back shortly.
Karen's body was found at High Craigton Farm on the north-western outskirts of Glasgow following a four-day search.
Police footage released today shows Mr Pacteau, dressed in black and joining his hands, in a police interview room. Mr Pacteau's head is slightly bowed while a policeman sitting opposite talks to him.
Meanwhile, police photographs also released today show the farm, located some 7km from Glasgow, and the double doors behind which Karen's body was found.
It has emerged that Pacteau first attempted to strangle the University of Limerick (UL) nursing graduate in his car before battering her to death with a heavy spanner.
The images also show Pacteau's Ford Focus car parked on Kelvin Street where he told police he carried out the horrible crime.
Soil found on the tyres of the car (see photos) matched soil found at High Craigton Farm.
Also released by Glasgow police are images of Pacteau's home at 11 Dorchester Avenue, including his bedroom where Karen's body was kept for a time.
CCTV footage can also be seen of Pacteau outside the Sanctuary nightclub on the night that Karen went missing.
He was also captured on CCTV buying caustic soda at B&Q in Glasgow. He tried to dissolve Karen's body after he killed her.
