THE sister of tragic Sinead Healey broke down in tears as she appealed to the public on national television to help catch her sister's killer.

Grieving Patricia Boyoumy plucked up the courage to appear on BBC's Crimewatch programme on Wednesday and make an emotional plea to the public to come forward with any information.

She pleaded with viewers, saying: "Anyone who knows anything, no matter how insignificant, please, please, please, contact the police, tell somebody because it is very important we get the people that did this to Sinead."

Sinead, 26, from West London, went missing after having a drink with friends on October 18 and the skeletal remains of her body were discovered by a passer-by in a lay-by off the A40, in Beaconsfield, on March 22.

Detective Chief Inspector Jim Dickie, from the Metropolitan Police, is leading the case, and revealed how one witness had spotted a dark coloured 4x4 near to where her body was dumped.

He said: "If you were the driver, come forward so we can eliminate you from our inquiries.

"Clearly if you saw who was driving and they were seen in suspicious circumstances, please ring and give us a name."

During a reconstruction on the programme of the events leading up to Sinead's death, viewers were told how neighbours heard strange 'banging noises' coming from her flat in Gliddon Road, Barons Court, West London, at around 1.15am on the night of her death.

DCI Dickie, said that Sinead's white bath robe with tartan piping, her mobile phone, keys and a pair of unusual ladies Nike trainers that fold down at the back into a sandal, were also missing.
