"A woman arrested after the deaths of her two children is expected to undergo psychiatric tests as she waits to learn whether a case will be brought against her. Rebecca Smith, five, and her brother Daniel, aged 11 months, were found on Tuesday in the resort of Lloret de Mar in Spain's Costa Brava. Their father was an on-the-run alleged paedophile who appeared in court on Wednesday. Their mother Lianne, 43, was arrested on suspicion of murder by Spanish police and will appear in court. Under the Spanish legal system, a suspect appears before a judge who decides whether there is sufficient evidence to bring a case against them. The infants' father, Martin Smith, appeared before magistrates in Carlisle accused of child sex offences. Smith, 45, originally from North Shields, had been one of Britain's most wanted men up until his arrest by Spanish police earlier this month. His wife and Rebecca had been reported missing from the Staffordshire area since December 2007."
