Neil Dalton's parents and brother today paid tribute to the 22-year-old trainee doctor murdered in Borneo, describing him as a "caring, thoughtful and witty young man".
Neil, described as a "brilliant trainee doctor" was stabbed to death in Malaysia, along with fellow medical student, Aidan Brunger.
Neil's parents, Jan and Phil Dalton, said: "We are just a normal family and we cannot believe what has happened.
"Neil was a caring, thoughtful and witty young man, who never thought twice about helping others.
"He achieved so much and made so many friends in such a short time. We are so very proud of him.
"Neil was a hard worker and very academic.
"He kept himself fit and was very sporty; involving himself in many football and cricket teams over the years.
"Neil enjoyed cycling and running and was always up for a challenge."
Neil's brother, Glen, said: "Neil was a best friend to many.
"This is evident from the number of his friends who have contacted me and referred to him as this and have passed on their happy memories that they shared with him. He will be sadly missed by so many."
Neil and Aidan were both on six-week placements as part of their studies at Newcastle University. They died in the early hours of last Wednesday.
Four men have been charged with the murders and, according to police in Borneo, have admitted they were responsible for the killings.
