mystery over her 31-year-old daughter's death.

Mrs. Gryneth Robinson's appeal followed Thursday's open verdict in the inquest on the tragedy.

Coroner the Wor. John Judge delivered his ruling after being told Debra Robinson died from drowning.

Pathologist Dr. John Winnick, however, was unable to say why she had drowned.

Mr. Robin McMillan, lawyer for the Robinson family, asked whether Miss Robinson could have been pushed from a rock, or boat.

Dr. Winnick accepted it was a possibility.

Miss Robinson's body was found last July floating just off North Shore, behind the Grace Methodist Church in Pembroke.

She had last been seen by her family when she borrowed her mother's car shortly before the tragedy.

The vehicle was found abandoned on Mount Hill, Pembroke, in the early hours.

Miss Robinson lived at Rockaway Drive, Southampton, and worked as a waitress at the La Trattoria Restaurant.

After her body was discovered, Police launched a hunt for a dark skinned male driver of an orange or brown old-type scooter.

The man had been spotted riding alongside Miss Robinson, and had been talking to her on Victoria Street behind City Hall.

Yesterday Miss Robinson's mother, a drug counsellor with Addiction Services, was being comforted by relatives.

She said she was pleased with the open verdict, and praised Mr. McMillan's representation of the family.

But she added: "The mystery surrounding the circumstances of Debra's death is still very much there.

"The coroner was only able to determine the cause of death. We still do not know the `hows, whens, and wheres' of Debra during the last 52 hours of her life.'' Mrs. Robinson appealed for anyone with information about her daughter's last hours to come forward.

"Only then can the mystery be solved,'' she said.

Mrs. Robinson added she had been pleased with the sensitivity displayed by the coroner, prosecution, and Police during the inquest.

Mr. McMillan said he believed Mr. Judge had reached the only possible verdict.

"I think it was consistent with the evidence. I would hope Mrs. Robinson appreciates as far as justice can be done it has been done.'' Mr. McMillan said Dr. Winwick's inability to say why Miss Robinson had drowned had been critical to the inquest's outcome.
