I guess this is St. Andrew Kim. The statue stands alone behind the St. Andrew Kim Catholic Church, the front of which is on Swiss Avenue. The church was built in 1911 as St. Joseph’s German Catholic Church for German-speaking Catholics. [The church congregation re-located after this photo was taken...they took the statue with them.]

This about St. Andrew Kim from a Catholic forum on the web:

Korean nobility; his parents were converts, his father a martyr. Andrew was baptized at age 15, then travelled 1,300 miles to the nearest seminary in Macao. He became Korea's first native priest, and the first priest to die for the faith in Korea. Leader of the Martyrs of Korea. Tortured and beheaded in 1846 at Seoul, Korea. Canonized 6 May 1984 by Pope John Paul II.
