Ex Miles City teacher in jail on suspicion of sex with underage student

MILES CITY – A former Custer County High School science teacher was booked into jail Tuesday on suspicion of multiple sexual encounters with a 15-year-old female student over a month’s time in December 2016 and attempting to conceal evidence.

Morgan Pett, 38, was charged with six counts of sexual intercourse without consent, one count of sexual abuse of children and one count of tampering with evidence, according to charging documents filed in April in Custer County District Court.

A Custer County jail worker said Pett was extradited on a warrant from Alaska, where he was working after he left his teaching job last year.
