A pedestrian walked up to a 27-year-old man who was outside his own home and shot him fatally Monday night. Then the assailant entered the home and killed a 17 year old who was there.
This happened about 6 p.m. in San Martín de Guápiles. The older victim was identified by the last name of Calderón.
Fuerza Pública officers detained a 23-year-old man a short time later on a local bus. They said he was the suspect.
