Under Spanish law, all crimes committed by minors can be expunged after 10 years once the offender reaches the age of 18. Under UK law, a conviction for murder is never considered “spent” in this way.Reporting restrictions were lifted after an appeal by the Oxford Mail newspaper, after the CPS dropped the case.A CPS spokesman said: “We keep all cases under continuous review so we can consider any new information that comes to light. In this instance, it emerged Ms Suárez González’s conviction was spent, which resulted in the charges being dropped.”A spokesman for Oxfordshire County Council, which oversees the school, said: “Recruitment is not the responsibility of the council, it is the responsibility of the individual school.”The school had followed safer recruitment processes in terms of the recruitment of this individual. We would stress this charge was not in any way related to any children at the school and only came to light after the staff member had left the school.”West Oxford Community Primary School was approached for comment.
