Crime Scene and Trauma Cleanup in Leupp, AZ

Leupp is a census-designated place (CDP) on the Navajo Nation in Coconino County, Arizona, pronounced "loop"; its Navajo name is Tsiizizii.

Leupp was named after Francis E. Leupp, who served as U.S. Commissioner of Indian Affairs from 1905 to 1909.

The population of Leupp was 934 at the 2020 census, down slightly from 951 at the 2010 census.

At the 2000 census, Leupp had 970 residents living in 228 households, with an average household size of 4.25 people.

In 1902 the Bureau of Indian Affairs established an Indian boarding school at Leupp, which was soon moved a few miles southeast to the site now known as Old Leupp.

In 1907 Leupp was designated the headquarters of the Leupp Indian Land, one of five separate Navajo agencies that existed before the Navajo Nation reorganized under a single government in 1936.

The Leupp Trading Post was built in 1910 by John Walker from quarried sandstone and operated under several owners until the late 20th century, when it closed and was dismantled.

During World War II the abandoned boarding school became the Leupp Isolation Center, which in 1943 held Japanese and Japanese American internees labeled troublemakers at other camps; about 80 people passed through it before it was returned to the Interior Department in September 1944.

Philip Johnston, who grew up near Leupp as the son of missionaries and learned Navajo there, proposed the Navajo code talker program to the U.S. Marines during World War II.

Leupp lies along the Little Colorado River about 45 miles southeast of Flagstaff, at an elevation of 4,754 feet, and covers about 13.6 square miles.
