ARREST OF CHILD RAPE SUSPECT
In March 2026, a former West Valley Junior High student reported to the Yakima Police Department that they had been in a relationship with one of their teachers. The Yakima Police Special Assault Unit was assigned the case.
Detectives with the Special Assault Unit interviewed the victim who described an assault that occurred in 2009, when they were 15 years old, involving their teacher at West Valley Middle School. An intimate relationship formed between the student and teacher and continued for multiple years until the teacher moved out of the city.

So proud of the person who came forward… it must not have been easy dealing with that trauma…
Wonder which teacher, i was in the jr high in 2009 but just two years prior i was at the middle school odds are i met or knew the teacher
Someone let me know when they release the name!!!
To the victim... So proud of you for speaking up! That took a lot of courage. 🙏
YPD does a great job whether people will admit or not! They work hard to keep us safe.
Why not come forward then? Why now? My thought that if it is true then the so called victim is not so innocent afterall. They knew what they were getting into, maybe he/she was blackmailing , extorting, ect or a strong argument broke out. And because they didn’t get their way they finally decided to spill the beans. Who knows if it even happened? But how can we know if it really happen? Especially if they come forward 17,18 years later? Foh.
It was Mr. Sissom, from what I found online
His name is Tyrone Sissom and was teaching at Evergreen middle school in Kent Wa
Release their name!!!
Good job YPD!

Patiently waiting for the name to be released…

West valley school district just sent a notice out. Tyrone Sissom taught at west valley junior high 2007-2008 and 2008-2009 and if anyone has any information to reach out to Yakima police.
Teachers name is Tyrone Sissom.
What led her to report it? She was happy for multiple years. Wonder where things went south. Was it right? No, but waiting years to report it is. Now she is a brave hero and he is a child rapistm.
Great Job YPD!
