A BRITISH chef found dead in his prison cell had been warned he was about to be charged with the murder of an Irish holidaymaker. A forensic psychologist had also determined Leigh Anthony Gardiner was fit to stand trial and could not plead an insanity defence. The 51-year-old was put on suicide watch after his June 2019 arrest for the savage Costa del Sol killing of "gentle giant" Irish holidaymaker John Pender in front of his wife and friends. Investigators heading two separate probes are expected to rule he killed himself at Alhaurin de la Torre prison near Malaga a fortnight ago after the twin setbacks.
