A Paradise Valley Unified School District (PVUSD) teacher committed suicide while fleeing arrest for the sexual abuse of a minor.
Steven Charles Mitten III, a history teacher at Shadow Mountain High School, fled from police on Wednesday shortly before taking his own life, according to a media advisory issued by the Phoenix Police Department (PPD) on Thursday.
Mitten, 65, previously worked at Cactus Shadows High School within the Cave Creek Unified School District (CCUSD). CCUSD awarded Mitten their Excellence Award in May 2018, given to one teacher in the school for outstanding contributions to students.
Per PPD, an unnamed adult female reported to law enforcement on Monday that Mitten initiated a sexual relationship with her when she was 16 years old. That relationship purportedly lasted for approximately three years.
The Crimes Against Children Unit (CACU) immediately investigated the woman’s claim and found probable cause to arrest Mitten.
The media advisory explained that Mitten fled from the Fugitive Apprehension and Investigations Detail (FAID) in his vehicle with a firearm. After law enforcement used a grappler to stop Mitten’s vehicle, Mitten turned his gun on himself and shot himself in his vehicle.
Detectives and the Special Assignments Unit (SAU) apprehended Mitten, and the Phoenix Fire Department transported him to a hospital. Mitten later succumbed to the self-inflicted gunshot wound.
PPD advised that other details were omitted from public communications given the ongoing nature of the investigation.
“This case reflects the unwavering dedication of our detectives, who work tirelessly on behalf of survivors, especially in cases involving crimes against children,” stated the advisory. “We recognize the lasting impact these incidents have on survivors and their families, and we remain committed to seeking justice while handling these sensitive investigations with care and professionalism.”
The Arizona State Board of Education (AZSBE) does not have any disciplinary records pertaining to Mitten.
Arizona Department of Education records reflect Mitten received a standard professional secondary certification covering history, political science and American government, and social studies for the sixth through twelfth grades in April 2021. Mitten also had a full endorsement for structured English immersion covering preK-12.
Another Arizona teacher was arrested this week for sexual exploitation of a minor. An elementary school teacher and high school coach, Timothy James Sonier, 48, was arrested on Thursday for uploading child sexual abuse materials. Sonier faces 10 counts of sexual exploitation of a minor.
Sonier taught at Dodge Traditional Magnet School and coached girls’ junior varsity basketball at Salpointe Catholic High School. Sonier has lived in Tucson for nearly 30 years; he passed a background check by Tucson Unified School District.
Prior to Dodge and Salpointe, Sonier worked at Dietz K-8 School, Catalina High School, and Sabino High School.
The AZSBE latest enforcement action report reflected that enforcement actions increased nearly eightfold from 2014 to 2024. AZSBE attributed this increase to the increased staffing and efficiency of case processing, not an upward trend of immoral or unprofessional misconduct in schools.
Although males comprise only 24 percent of total educators, they represented 61 percent of all enforcement actions.
A majority of enforcement actions since 2012 have come from sexual offense cases (671 out of 1,876 cases, or 36 percent). These cases are not distinguished between offenses against minors versus adults. In 2024, 29 percent were associated with sexual misconduct behaviors.
AZSBE has not published its enforcement action report for 2025 as of this report.
