If it is indeed suicide (and surely that must be pure speculation at the moment) it is probable that even his close friends and relatives know nothing about his intentions. Many years ago my uncle took his life by suicide, drowning himself in a local pond. Although he had a few medical issues, none of them life threatening, nobody thought he would do this and it came as a total bolt out of the blue when he did. As a teenage lad you imagine it upset me immensely. We will never know what was going through this chaps mind before he took off.
