Sumantra Maitra - Calcutta, India
Detectives investigating the rape and killing of Scarlett Keeling are in a serious state of panic. At first they said her death was due to drowning. Then, after a second post mortem that revealed terrible vaginal injuries as a result of an extremely violent sexual assault, they said she had been murdered.
Keeling, 15, of Bideford, Devon, was found drowned last month. Police initially said she had died after drinking too much. Local barman Samson D'Souza, 29, has been charged with rape but not with murder.
Goa's Tourism Minister Francisco Pacheco has stated that Indian police deliberately covered up Miss Keeling's murder. He told the Reuters news agency: "This is a clear case of murder and it has gone out of proportion because police tried to cover it up."
A murder inquiry was eventually started on the recommendation of doctors who examined Keeling's body.
D'Souza told the court in Mapusa on Monday that he was with Keeling the entire night and left her at 0500, but she was still alive then.
He was detained by police after witnesses said they saw him with Keeling shortly before her body was found at the Anjuna resort on February 18, which is popular with Western dance music party crowd. Fiona MacKeown, Keeling's mother, was on a six-month holiday with her boyfriend and six other younger children when her daughter died.
The rest of the party were travelling to a neighbouring state while Keeling stayed with a tour guide in popular Anjuna. MacKeown, who has said from the beginning that her daughter was sexually assaulted and murdered, has criticised the police investigation.
She told BBC News: "I'm not confident that they've got the right person, I think they're just making a public show to be honest. We've had many reports that they've done this before with other cases for a start-off and I just think they're going to continue to try and cover themselves up and their mistakes."
She said she thought it possible more than one person was involved in the killing. A second post-mortem examination discovered there was not enough water in the dead girl's lungs for her to have drowned.
The doctors who carried out the latest examination discovered some 50 bruises and abrasions on Keeling's body and unanimously recommended police open a murder inquiry into the death. MacKeown, who described Keeling as "a really affectionate, loving girl", is preparing to fly her daughter's body back to the UK before returning to India to help with the investigation. D'Souza has been remanded in custody.
He was remanded in custody for 14 days, the same as D'Souza, to give police more time to quiz him.Carvalho was detained on Wednesday after giving himself up voluntarily. Police allege Carvalho intentionally supplied ecstasy and possibly other drugs to Keeling before she was raped.
Her lawyer, Vikram Varma, said on Thursday that he expected further arrests in connection with the rape and murder.Miss Keeling's naked and battered body was found on a beach in Anjuna three weeks ago.
MacKeown is waiting for a response from India's prime minister to her claims there was a police cover-up over her daughter's death.In a letter to Manmohan Singh, Ms MacKeown, said: "I have no faith in the leadership of the Goa police. The administration tried its best to hush up the death as a simple case of drowning."
Speaking in Anjuna, Goa's police Inspector General Kishan Kumar said that once the police investigation had come to a conclusion about the rape and murder of Scarlett "we will look into other aspects".That could include the possible neglect of the teenager, said Kumar.
MacKeown had left her daughter at the resort with a friend while the rest of the family travelled further afield. The mother, who has denied neglecting her daughter, said: "I think I was probably naive and too trusting of the people around her that claimed to be her friends, but that was probably the worst thing I have done."
