The inquiry into the death of Greater Manchester Police Chief Constable Michael Todd will look into the possibility he committed suicide.
The 50-year-old father-of-three was found dead near the summit of Mount Snowdon, north Wales, on Tuesday afternoon, his body covered in snow.
He is believed to have killed himself and sources said letters addressed to his family have been found.
A post-mortem examination is taking place at Ysbyty Gwynedd Hospital.
His body has been formally identified by a colleague from Greater Manchester Police.
Mountain walk
Mr Todd had been off duty on Monday and had spent the day walking in the Welsh mountains.
The search for him began in the early hours of Tuesday, but it was later in the day that hill walkers reported seeing a body near the summit of Snowdon.

His body was found on part of the mountain called Bwlch Glas at about 1500 GMT.
His body was carried down from the mountain despite poor weather conditions.
Tributes have continued to be paid to Mr Todd, who had been tipped as a future Metropolitan Police Commissioner.
Deputy Chief Constable of Greater Manchester, Dave Whatton, said staff in the force were "absolutely shocked" by the death.
The President of the Association of Chief Police Officers (Acpo), Ken Jones, said: "Mike has made an enormous contribution to policing in Manchester and nationally throughout his distinguished career.
"The news of his death is a tragedy and he will be greatly missed by chief officer colleagues and all who worked with him during his career.
"As a personal friend and valued supporter, I will miss him greatly."
'Decent and committed'
Bernard Hogan-Howe, Chief Constable of Merseyside and Chair of North West Regional Association of Chief Police Officers, also paid tribute to Mr Todd.
"This is a terrible shock. It's a great tragedy for Michael's family and all the people who work with him," he said.
"Michael was a great character, who was full of life and enthusiasm."
Former Home Secretary, David Blunkett, described Mr Todd as a "decent and committed policeman who did a first-class job in difficult circumstances".
"His death is a real tragedy and I personally feel very sad to hear of his loss."

Profile of Michael Todd
Tributes to chief constable
Mr Todd was appointed chief constable in Greater Manchester, England's third largest force, in October 2002, following the retirement of Sir David Wilmot.
He had been a police officer for more than 30 years, having joined Essex Police in 1976.
An inquest into Mr Todd's death is to be opened and adjourned at Anglesey Council chamber on Thursday afternoon.
Books of condolence in memory of Mr Todd have been opened at Manchester Cathedral, Trafford Town Hall and Old Trafford Library.
People can also sign an online book of condolence on the Greater Manchester Police website.
Very sad, a greatly respected officer and will be sadly missed.
A very strange set of circumstances, and a most regrettable death. Condolences to family and friends.
You know this happens far too much for my liking. If this officer has in fact committed suicide it will be another one in such a long long list. We have recently over here had a large number of officers in various jurisdictions kill themselves.
To me it is so important to keep on top of your yourself and your mind. You should never be afraid to seek help or see someone if you have the feeling of not being able to go on. This also is the case when the images, memories etc of what we see everyday suddenly get replayed in your mind.
It is also important for us all to watch our friends and colleagues closely. This job we do is extremely stressful and there will be times when our mates don't do so well. We all must watch them carefully and if need be intervene with help before the worst occurs.
My deepest condolences to the officers family and friends.
RIP my brother, your fight is now over.
It does seem though that getting help is not always the 'in' thing to do, however stupid that sounds. RIP again
