Ms Fang’s brother told CNA earlier this month that the two witnesses were close friends with his sister.
He said he was surprised Ms Fang would have a close relationship with Ong. He added: “My sister was a down-to-earth, stay home kind of woman. The suspect is apparently the direct opposite.”
The victim’s family is calling for “as much justice as possible”, said Mr Martinez on Wednesday.
He said he would request a jail sentence of 20 to 25 years for Ong if he is found guilty of killing Ms Fang.
Ong has not been charged and remains detained in Sangonera prison in Murcia. Under Spanish law, a person can be on pre-trial detention for up to two years. This can be extended by another two years for serious offences.
According to sources close to the case, he has not yet given a statement to the authorities. A suspect has the right not to do so, under Spanish law.
ECONOMIC MOTIVE
Mr Martinez said the Civil Guard, a national police force in Spain, is still investigating a possible “economic” motive behind the killing.
Mr Fang previously told CNA that his sister had nominated Ong to be the beneficiary of her Central Provident Fund (CPF), a mandatory social security savings scheme.
She made the nomination in person in October last year, about six months before she was found dead.
Around the time Ms Fang nominated Ong as her beneficiary, almost S$200,000 (US$148,000) was deposited into her CPF account. Mr Martinez said Ms Fang’s CPF account has more than €430,000 (US$462,000).
“If the CPF Board is informed of any facts or circumstances which may affect the validity of the CPF nomination, an investigation will be conducted by examining the evidence and supporting documents to ascertain the validity of the CPF nomination,” said the statutory board on Jun 3 in response to CNA’s queries.
“For CPF nominations that are contested posthumously, CPF Board will withhold the distribution of the deceased member’s CPF savings till investigations are completed.
“If the nomination is found to be invalid, CPF savings will generally be distributed based on an earlier nomination if any, or according to intestacy laws.”
