Wastwater diver Carl Morris died of heart attack, inquest told
A man died after suffering a heart attack while diving in a Cumbrian lake, an inquest has been told.
Carl Morris died at Wastwater on 27 January 2013 after getting into trouble at a depth of 164ft (50 metres).
The 39-year-old, of Huddersfield, West Yorkshire, had travelled to the Lake District to complete a course and was part of an experienced group of four.
The inquest, which is being held at Cockermouth, is expected to end on Thursday.
Dive leader John Timperley told the hearing he had held hands with Mr Morris as they began to ascend but they lost contact at 39ft (12 metres).
He added that Mr Morris would have dropped "like a stone".
Earlier, the inquest was told Mr Morris - himself qualified to instructor level - did not have a valid medical certificate.
A post-mortem examination found he died from a heart attack as a result of a blocked coronary artery.
The inquest was told Mr Morris was 6ft 1in tall (1.8 metres), a heavy smoker and his weight fluctuated between 17 and 21 stone (107-133kg).
His body was found after a two-day search.
The initial operation had involved police, fire, ambulance and mountain rescue teams as well as an RAF helicopter.
