Nampa teen indicted on attempted murder charge in high school stabbing

A grand jury this week determined that there is enough evidence that a 17-year-old high school student tried to kill a fellow student to proceed to a trial, according to the Canyon County Prosecutor’s Office.

Wyatt Weist was indicted on a charge of attempted murder Wednesday. He is accused of stabbing his ex-girlfriend in the parking lot of Columbia High School on Dec. 4.

Weist is a juvenile, but the case will not be in juvenile court. State law requires that Idaho juveniles 14 and older be tried as adults if they are accused of violent crimes.

Weist was scheduled to go to a preliminary hearing in late December, but that hearing was rescheduled and later canceled. Rather than present evidence to a judge at a public hearing, prosecutors opted to present it to a grand jury, according to county spokesman Joe Decker. Grand jury proceedings are not open to the public.

Weist told a Nampa police detective that he was trying to kill his ex-girlfriend when he stabbed her in the chest, abdomen and arms in a high school parking lot, according to the probable cause affidavit.

The girl, 17, broke up with Weist in October, and there was “a lot of drama” after that, Weist told the detective. She was transported to a local hospital for treatment.

“All my frustration is directly related to (her),” Weist told the detective, according to the document. “When I was in a relationship with her … I felt very strong feelings for her and all I wanted was to give her love and support … and she just left me … saying she wasn’t interested in me. I blame her for my mental state today.”

Weist said his father bought him the knife, and he carries it only if he feels the need.
