SKEGNESS, England (AP) _ A man driving home after an overseas vacation rushed to help victims of a coach crash and discovered his mother was the sole fatality, a relative said Tuesday.

Simon Miles, 24, arrived minutes after a coach skidded on a rain-slicked turn in the highway and overturned into a ditch Monday near his east coast hometown of Skegness, said Irene Jacklin, his grandmother.

He had just driven 150 miles from London's Gatwick Airport after a vacation in Malta. His 50-year-old mother, Marian, was returning the same day from a vacation in Italy.

Mrs. Jacklin said her grandson ran to the coach when he heard cries for help and the first person he helped out of the wreckage turned out to be his mother's friend, Jack Milburn.

''Then it came to him that his mum was in there,'' she said. ''He couldn't bring himself to go back inside. It was a terrible shock for him when he realized she was dead.''

Eight other people in the coach suffered minor injuries.
