She added the man showed no sign of being under the influence of drink or drugs.
The victim was hospitalised in Santa Cruz and although her death was not linked to the attack, her daughter testified that her health worsened following the brutal assault.
The rapist was arrested in Valencia two months later and insisted he had nothing to do with the assault. He denied fleeing the island and said he had left Tenerife the following day purely for work reasons.
He was spotted on CCTV footage and also identified by a woman he had mugged the same day, although the court case was reportedly dogged by delays.
In addition to his sentence, the man was ordered to pay £30,000 to the woman’s family and to return the jewellery, with the possibility of further compensation.
