A Spanish woman found dead alongside her British partner and two children in Gibraltar is believed to have killed her family before taking her own life. Anarda De La Caridad Perez Friman, 37, is said to have been 'suffering from post-natal depression' when she allegedly stabbed John Joseph Shannon, 31, the couple's six-week-old baby and her daughter, four. Mr Shannon, from Liverpool, had initially been accused of killing his partner and the two children, but police now believe Perez Friman, a Spanish national of Cuban descent, to be the culprit. Scene: John Joseph Shannon, from Liverpool, was found dead alongside his partner Anarda De La Caridad Perez Friman, 37, their six-week-old baby Eve and Perez Friman's daughter . The couple and the two children, identified as Eve Shannon Perez, and Amanda Kristoffersen Perez, Perez Friman's daughter from a previous relationship, were found dead earlier this week. According to police, the scene was so horrific that the officers who found their bodies were offered counselling. The family, who lived in Estepona, Spain, had arrived in Gibraltar on March 25, and were staying in an apartment in the Boschetti Steps area owned by a family friend. Perez Friman is said to have suffered a 'psychotic incident' as a result of post-natal depression, and stabbed her partner and the two children before taking her own life, the Sunday Express reports. According to the newspaper, Mr Shannon's body was found with defensive wounds which suggest that he has been trying to protect the children before being killed. Accusations: Initial reports indicated that Mr Shannon was responsible for the gruesome killings, but police now believe that Perez Friman suffered a 'psychotic incident' as a result of post-natal depression . Acting superintendent Wayne Tunbridge, who is leading the investigation, said: 'We are not looking for anyone outside of the family at this stage but we have numerous lines of enquiry. 'We are in communication with the family members of the four deceased who now must come to Gibraltar before we release any details about the individuals. The family were found in the rented flat in the Boschetti's Steps area at 11.35am on Monday. Royal Gibraltar Police said the family had been living in Estepona, Malaga before arriving in Gibraltar and 'it is understood that it was their intention to travel to the United Kingdom'. Gibraltar police is now awaiting the results of postmortem examinations conducted by Home Office pathologists.
