The Columbia High School student who police say attacked his ex-girlfriend with a knife in the school parking lot will be charged as an adult for attempted murder in the first degree.

Wyatt Weist, 17, told a detective he was trying to kill the girl after he attacked the victim at about 1:12 p.m. Monday, according to probable cause affidavit provided by the Canyon County Sheriff’s Office. Weist attacked her with a knife and wounded her in the abdomen, chest and arms. She was transported to Saint Alphonsus Medical Center.

According to Idaho statute, any juvenile age 14 to 18 alleged to have committed attempted murder will be tried as an adult.

According to court documents, Weist and the victim had previously been in a romantic relationship that ended in October. The two had been messaging back and forth via Facebook and decided to meet after third-period classes near her car to discuss “a lot of drama (that had been) going on,” according to documents. The two began to argue, which led Weist to attack, according to the affidavit.

“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.”

The victim told a detective Weist was “blindly hitting her with that knife” and “was cutting whatever he could.”

Weist said his father bought him the knife and that he did not always carry it with him, telling detectives he “only (carries) it if I feel the need to.”

Weist also told detectives he had previous thoughts of stabbing the victim after their breakup but “never acted on them,” documents said. He also admitted to the detective that he previously had suicidal thoughts, according to the affidavit.
