Investigations into the violent death of an entire family in their Gibraltar home point to the murderer being the mother. It appears from the forensic evidence that her husband died having died trying to shield their small children from the attack.
British national John Shannon, 31, from Liverpool and his 37-year-old wife Anarda de la Caridad Pérez Friman - originally Cuban but a Spanish citizen - her unnamed four-year-old daughter from a previous relationship with Danish national Rene Kristtoffersen, and John and Anarda's six-week-old baby daughter Eve were found stabbed to death in an apartment they had borrowed from a friend in the Boschetti's Steps area of the Rock.
The family had lived in Estapona, in the province of Málaga for some years and were on holiday for a few days in Gibraltar, according to police in the British enclave, and had planned to go back to the UK for a trip to introduce the new baby to the family.
Top UK Home Office pathologist Nathaniel Carey, who travelled from London to perform the autopsies, confirms John's fatal injuries were sustained when he tried to protect the two little girls from their knife-wielding mother. He and the children sustained mortal wounds to the neck. Anarda, after killing all three of them, slit her wrists, the pathology report claims.
Sources close to the family - including Kristtoffersen, who lives on the Costa del Sol - claim Anarda was suffering from post-natal depression and was given to psychotic episodes.
The Royal Gibraltar Police said at the time of the gruesome discovery that they 'were not looking for anyone else' in connection with the crime. This initially led the Spanish press to jump to conclusions that the wife had become a victim of gender violence, largely due to three other high-profile cases of marital murder having hit the headlines that week.
But the reality, say detectives, was the other way round - it was the husband who had lost his life in a horrific episode of domestic violence.
The family were found when their friend who had lent them the apartment, an Australian man, returned home with his young children and saw blood seeping out from under the door. When he tried to get into his rented flat, Anarda's body was blocking the entrance.
Officers called out to the crime scene were said to be so distressed they needed counselling afterwards, which was provided by the Gibraltarian government, led by Chief Minister Fabián Picardo QC. Speaking of the tragedy, Picardo said that 'as a husband and father', he was 'in total shock'.
Gibraltar had not been the scene of a murder in nearly five years until then.
Police said the circumstances of the Gibraltar case 'appeared pretty cut and dried' before Dr Carey examined the bodies, but that it was 'standard procedure' to conduct an autopsy before a verdict was passed.
Postpartum depression is reported to affect between one in 10 and one in seven new mothers, but the UK's Royal College of Psychiatrists and the British charity Pre- and Post-Natal Depression Advice and Support (PANDAS) say post-natal psychosis, which is what Anarda was said to be suffering from, is extremely rare. Statistics show that it affects fewer than one in 1,000 women.
