Tony Myers posted the following on his Facebook page to ry and clarify the circumstances around this tragedy
"Understandably lots of people who cared about Liam want to know what happened to him. His family are happy for me to share this with everyone.
We have patched together the following from what different people know. It appears Liam took some sleeping tablets and pain killers on his flight back to the UK from a seminar he did in the USA (he had an old neck injury and was very tired but couldn't sleep). He got back home after collecting his new car and had a couple of alcoholic drinks and possibly took some more tablets (we are not 100% sure). He went for a walk to clear his head and get some fresh air and asked Pardeep (his wife) to go to the gym to cancel training as he didn't feel up for it. Liam didn't return home and was found unconscious next morning suffering from hypothermia in a local park (the doctors suspect he may also have had a cardiac arrest too as he was only 18 degrees C when he arrived at hospital). He received resuscitation from the very public spirited people who found him while walking their dog . In intensive care he was gradually warmed up but his organs were too damaged by the cold to recover despite the doctor's best efforts and all the best care.
