A former Pleasant Hill R‑III teacher from the Kansas City area is now facing serious felony charges tied to an alleged sexual relationship with a student that dates back more than a decade.
Mark F. Amos, who lives in Independence, was arrested this week and charged with three counts of second‑degree statutory rape connected to a reported sexual relationship in 2009–2010. The woman who came forward told investigators she was under 17 at the time. District officials told reporters that Amos is no longer employed by Pleasant Hill R‑III.
Listed As Teacher And Coach In District Materials
District documents show Amos embedded in both the classroom and on the field.
The Pleasant Hill R‑III online directory lists “Mark Amos” as a science teacher, according to the Pleasant Hill R‑III staff directory. A separate athletics listing names “Mark Amos” as an assistant football coach on the high school’s roster, as shown on the school’s Eventlink activities page.
What Investigators Say Happened
Court documents obtained by KMBC describe an alleged ongoing sexual relationship between Amos and the victim in 2009–2010, when she says she was under 17.
The filings allege that sexual encounters happened multiple times in Amos’ car and at his home. Investigators say they searched his phone in March 2026 and found about 10 screenshots of the victim’s social media accounts, reportedly saved over roughly five years.
According to those same court papers, investigators also point to communications between Amos and people advertising sexual services and list about 40 phone numbers tied to negotiations for in‑person meetings. Prosecutors have charged Amos with three counts of second‑degree statutory rape, and a bond‑review hearing is scheduled for July 22, 2026.
What Missouri Law Says
Under Missouri law, second‑degree statutory rape covers sexual intercourse between a person who is 21 or older and someone under 17. It is a Class D felony that can bring prison time; the offense is codified in RSMo §566.034.
What Happens Next
Court filings state that Amos was read his Miranda rights after his arrest and asked for an attorney. He remains presumed innocent while prosecutors and defense counsel prepare for the upcoming bond‑review hearing and any future court proceedings.
