A body found last Sunday morning, 14 January, on El Oasis beach in Marbella is believed to be Rebecca Muldoon, the 35-year-old British woman missing since the beginning of the year.
Police sources confirmed that the body belongs to a woman aged between 35 and 40 and that the physical features and clothing coincide with those of the missing mother-of-two.
According to the inquiry, no third party is thought to have been involved in her death and the initial results of the autopsy point to suicide.
Investigators are awaiting the results of DNA tests to confirm the identity of the body. Meanwhile Muldoon's family is collecting funds for an eventual repatriation.
Muldoon was reported missing on 2 January when a neighbour told police that the woman's children, eight and eleven, were alone at their home in the Vigil de Quiñones area of Marbella.
Rebecca's disappearance came after she had reported her partner, Paul Muldoon, for domestic violence but then failed to attend court to confirm her allegations.
Her husband was in custody over the allegation at the time of her disappearance.
After the neighbour alerted the police to the fact that the children were at home alone, Rebecca's family were notified and travelled to Marbella to take care of them.
Local Police, fire and Protección Civil officers were involved in last week's search operation which found no clues to the woman's whereabouts.
In a further development, the National Police arrested Paul Muldoon, 33, for a second time in response to a European arrest warrant which came into force on Monday.
This detention is in relation to a finance-related offence committed in the UK, and is not connected to the disappearance of his wife.
Paul Muldoon stands accused of fraud concerning financial products worth 900,000 euros.
He is also facing charges in Spain for endangering public health after more than 400 electronic cigarettes containing cannabis oil were seized from an office he rented in Marbella.
These were discovered after investigations into the crime committed in the UK pointed towards other possible illicit activities.
Some 425 e-cigarettes of three varieties and with a high concentration of tetrahydrocannabinol (84 per cent) were discovered in the offices.
They were manufactured in California and imported to Spain supposedly without having undergone any health inspection.
Investigations suggest that they were about to be sold in smokers' clubs and exported to the UK.
Paul Muldoon appeared before a judge on Wednesday in Marbella in relation to the public health offence and is awaiting extradition procedures for the charges he faces in the UK.
