David Brown looks at the puzzles and mysteries at the heart of the four month investigation

What happened in the four hours before Madeleine was reported missing?

Kate and Gerry McCann claim that while they dined at a restaurant with friends regular checks were made on Madeleine and their two-year-old twins, Sean and Amelie, at their nearby holiday apartment. Mr McCann told police he saw his daughter asleep at about 9pm. A friend, Matthew Oldfield, entered the apartment at about 9.30pm but did not look in the bedroom Madeleine and the twins were sharing.

It is not known if anyone apart from Mr and Mrs McCann saw Madeleine alive between 6pm and 10pm, when she was reported missing by her mother. The timing is crucial but would be only circumstantial evidence in any prosecution. Although a small child could be killed quickly it would take time to hide a body so that it was not discovered in the biggest search in Portuguese history.

Why did Kate McCann cry out “They’ve taken her?” when she discovered Madeleine missing?

Portuguese police are reported to find it suspicious that Mrs McCann immediately believed that more than one person had taken her daughter. This could suggest that she knew who had taken Madeleine, perhaps people who thought they were helping Mrs McCann by removing her daughter’s body.

Alternatively, it could be an off-the-cuff remark by an hysterical mother or perhaps was misheard or misunderstood in the confusion of the night.

What were the movements of the McCann’s friends on the night Madeleine disappeared?

The McCann family had stayed at the Ocean Club resort with three other British couples and their five children, and a single woman. Russell O’Brien, a doctor from Exeter, left the restaurant for half an hour to look after his own daughter, returning shortly before Madeleine was reported missing.

His wife, Jane Tanner, was the only witness to report a man carrying away child from the McCann’s apartments. There is confusion about when members of the party arrived at the tapas restaurant and left to check on their own sleeping children.

How much alcohol did the McCanns and their friends drink on the evening Madeleine disappeared?

Kate and Gerry McCann and their friends are reported to have told detectives they shared four bottles of wine, with another two barely touched before Madeleine was discovered missing.

However, it is claimed detectives have recovered a bill showing they downed eight bottles of red wine and six white during the afternoon and evening.

Why was Madeleine’s bedroom window and shutter open?

Kate and Gerry McCann told police that the window shutter in Madeleine’s bedroom, which could not been seen from the restaurant, had been forced open.

Police tests showed the heavy metal shutter had not been forced up from the outside, so must have been pulled open from inside the room. Assuming that the abductor entered through the apartment’s unlocked patio windows, why would he or she not leave by the same way or the use the front door?

Or was the window opened to make it appear as if an intruder had used it to enter the bedroom?

Why did Madeleine’s sister and brother sleep through her “abduction”?

Sean and Amelie were heavy sleepers who were not disturbed by their sister’s abduction, claim their parents. However, they also slept through their mother’s hysterical response to Madeleine’s disappearance and the presence of dozens of people who joined the search before being carried out by a female police officer. Kate and Gerry McCann have strenuously denied sedating their daughter.

Why were the McCanns allowed to leave Portugal if they are suspects?

The Portuguese authorities allowed the McCanns to return to the UK after they agreed to reside only at their home in Rothley and to return for further questioning if necessary.

Portugese law states that after someone is declared a suspect, police have eight months to conclude the investigation into that individual. If they require further time officers can apply to the courts for a four-month extension.

If the McCanns refused to comply with a request to return to the Algarve for interview, Portuguese police could issue a European Arrest Warrant under which extradition can be carried out within six weeks.

Why has it taken so long to find the evidence that could implicate Kate and Gerry McCann?

The material was only collected at the end of July and early August in a review of the investigation carried out by Portuguese detectives with the help of British police and two sniffer dogs. Many of the samples are very small, containing just a few cells, while others are of poor quality because of damage by cleaning or simply the passing of time.

A full report of the findings will not be ready for weeks, but many results have already been passed to the Portuguese authorities.

What evidence were police looking for?

Detectives are searching for any evidence that proves Madeleine is dead or contradicts the accounts of Mr and Mrs McCann and other witnesses.

It appears the Forensic Science Service believes it has discovered compelling new evidence, possibly from more than one source. Portuguese detectives told Mrs McCann repeatedly that they found traces of Madeleine’s blood in a Renault Scenic hired three weeks after she disappeared, suggesting that the missing girl’s parents used the vehicle to carry her body. It is possible to tell if the blood came from a living person or from a corpse, and even the time of death. However, some reports suggest that the quality of the blood sample was too poor to confirm the origin while others have denied any blood was found in the vehicle and claim it was other “bodily fluids”. Unless a body had been placed in a freezer, it would have badly decomposed during the warm weather; leaving a mass of traces invisible to the human eye.

Does any trace of Madeleine in the hire car prove she was killed?

No. Mr and Mrs McCann hired the car to buy new clothes in the town of Portimão a day before they flew to Rome to see Pope Benedict XVI. They then used it regularly for family outings and to collect friends and relatives from Faro airport. They continued using the car until shortly before flying home yesterday. Kate and Gerry and their two-year-old twins would have often carried in the car items used by Madeleine. These items could easily certainly carry Madeleine’s hair and minute traces of skin, dried blood, saliva and vomit. The same could be said of the holiday apartments used by the McCanns and their friends in the Ocean Club resort. However, if the blood came from Madeleine’s corpse the only other highly unlikely explanation would be that a previous hirer had moved the body.

One report suggested yesterday that Madeleine’s DNA had been found on the floor of the McCanns holiday apartment, but because of degredation it was based on an incomplete picture, with only 15 of the 20 genetic markers usually used for such analysis.

What about the discoveries of the “cadaver” sniffer dog?

Mr and Mrs McCann were shown a police video of a sniffer dog used to find corpses “going crazy” when it approached the hire car. Reports also claim that is discovered the scent on the vehicle’s key fob. Mrs McCann is reported to have explained that in her work as locum GP she came into contact with six corpses in the weeks leading up to Algarve holiday.

This seems a high number for a locum GP working just a couple of days a week but would be easy to check against surgery records.

The crucial difficulty with the sniffer dog “evidence” is that it cannot distinguish between corpses. This type of dog is trained to find bodies, not identify where dead bodies have been. Crucially, they can become excited by other scents.

Any evidence of Madeleine’s death on Cuddle Cat?

The cadaver dog is alleged to have become excited when shown Madeleine’s favourite soft pink toy, called Cuddle Cat. The cat had become poignant symbol of a mother’s loss as Kate McCann carried it with her at all time from the night of Madeleine’s disappearance.

She washed it four days after the police tests, claiming it had become dirty. The toy was potentially crucial evidence and should have been seized by police very early in the investigation.

What evidence can be found in Mrs McCann’s Bible?

Mrs McCann, a devout Roman Catholic, claims that police told her that a crumpled page in her Bible was evidence that she was involved in the death of her daughter. The page contained a passage from Samuel II, chapter 12, verses 15-19, which recalls how man’s child is stricken with illness after he “scorns” the Lord.

The man fasts for seven days, refusing to get up off the ground, to try to gain redemption — but eventually his child dies. Mrs McCann claims that detectives told her that damage to the page proved she had been reading it.

Why are the McCanns suspects in their daughter’s killing?

Portuguese police refuse to say why the couple have been made official suspects. Under Portuguese law police can not question someone as if they had committed a crime unless they are a “suspect”. It could simply be that police wanted to ask the couple about the evidence they had collected, and that the seriousness of the process has been misunderstood and exaggerated by cultural and language differences. The McCanns believed that they were about to be charged with Madeleine’s death, but it does not appear police disclosed any crucial evidence to them.

All parties have strenuously denied any wrongdoing.

Detectives also suspect husband Gerry, 39, helped cover up the death by disposing of the body.
