Buckeye, Arizona’s Keith Armstrong arrested; Surprise music teacher on administrative leave


Keith S. Armstrong, 65, of Buckeye, Maricopa County, Arizona, United States is a music teacher at Legacy Traditional School – West Surprise in Surprise, Maricopa County. He owns A’S Band Instrument Repair, which is based in Buckeye.

Aside from Buckeye, Armstrong has lived in other parts of Arizona including Maricopa, Phoenix and Tonopah. From 1973 to 1976, he went to Camelback High School in Phoenix.

From 1979 to 1981, Armstrong attended Grand Canyon University in Phoenix where he earned his bachelor’s degree in music education. In December 2013, he traveled to London, England, United Kingdom.


Since October 2022, the Buckeye Police Department has been reviewing multiple cyber tips from the National Center for Missing and Exploited Children. Investigators tracked dozens of apparent child porn images to a unique internet protocol address leading to Armstrong’s residence in Buckeye.

On May 23, 2023, Buckeye Police Department officers served a search warrant at Armstrong’s home. They found 10-25 files of child pornography stored on a drive that belonged to the music teacher and arrested him.


During an interview, Armstrong told investigators a stranger told him to look into pornographic material and that he had been moving from content depicting adults to children. He said he was having issues becoming aroused after battling with the new coronavirus (COVID-19).

Armstrong was charged with 10 counts of sexual exploitation of a minor. On May 26, 2023, a Legacy Traditional School – West Surprise spokesperson confirmed that he was placed on unpaid administrative leave and prohibited from having access to school grounds while the investigation is ongoing.
