A minor is one of two persons detained in Limón in the murder of a guard at a school.
The dead man was identified by the Judicial Investigation Organization by the last name of Contreras. He was 42.
The guard was supposed to have the day off Saturday, but he returned to his workplace to do some needed maintenance, said judicial agents. He appears to have interrupted a burglary. He was shot once in the head, said agents.
A 23-year-old man was detained late Saturday as well as a minor who may be as young as 12.
