The Cerro San Miguel is the fourth highest mountain of the Cerros de Escazú, Costa Rica 2,035 m (6,677 ft)[1]. San Miguel makes reference to Saint Michael.
In 1933 a 26-meter-tall iron cross was installed on the top of the mountain, and is known as the Cross of Alajuelita. It is lighted by night since 1984 and has become a reference point in the Central Valley, from where it can be seen to the south. The cross is a popular pilgrimage destination and can be easily visited on a one-day hike.
It was at this site where the Crime of Alajuelita took place on April 6, 1986. Seven women, six of them children, were on a day trip to the cross when they were shot, supposedly by the 'Psicópata', a still unidentified serial killer, in the first of eight crimes[2][3].
