SPAIN, Feb 10, (Agencies): Two Russian adolescents have been apprehended in Spain, facing allegations of murdering their adoptive mother earlier this week. Silvia López Gayubas, 48, was discovered deceased on Wednesday night in Castro Urdiales, Cantabria, found inside a car in the garage of her family residence. The grim scene revealed a bag over her head and signs of "blows and a stab wound to the neck."

Around 9 pm, Spain's Civil Guard found the lifeless body, prompting an immediate search for her two missing teenage sons, both of Russian origin. The search concluded around 2 am when the teenagers, aged 15 and 13, were located in a local park. Shockingly, the teens had reportedly orchestrated a fake kidnapping, even calling their grandmother about the alleged abduction. The boys' father, working overnight, was initially skeptical and devastated upon learning of the false claim.

The Investigative Court No. 5 of Santander has ordered the eldest child's "closed confinement" for six months, and he is slated for admission to the Parayas Youth Socio-Educational Center. As the younger child is 13 years old, he cannot face charges. Both youngsters, adopted from Russia, were transferred to the Armed Institute Command in Santander following the alleged crime.

The younger child is currently placed in a child protection center, awaiting transfer to the Juvenile Prosecutor's Office for a psychosocial evaluation. A prosecutor will then determine whether to seek a "precautionary measure" from a juvenile judge.

Despite the shocking incident, there were no prior complaints about the family, and no history of violence had been reported. As of 1:30 pm local time Thursday, the alleged weapon has not been located by the Civil Guard of Spain.

Expressing her dismay, Susana Herrán, the mayor of Castro, commented on the tragic news.
