Jacob Matthew Aubuchon, 18, of Pevely has been accused of stabbing another man at least two times during an altercation at a party in the 7200 block of Linda Lane north of Hillsboro, according to court documents.
Aubuchon was arrested and charged Jan. 16 with first-degree assault, a class B felony punishable by five to 15 years in prison; and armed criminal action, an unclassified felony that carries a penalty of three to 15 years in prison. As of Monday, Jan. 19, he was being held without bond at the Jefferson County Jail in Hillsboro, court records show.
According to the probable-cause statement filed in the case, the alleged victim was stabbed at least twice in his back on Dec. 20. The man who was stabbed was treated for non-life-threatening injuries at an area hospital.
The man, who was stabbed, told Jefferson County Sheriff’s Office deputies he and his friends were confronted by a group of men at the party. The man said he started to argue with Aubuchon, and the man said Aubuchon tried to attack him with a knife, the report said.
The man said he punched Aubuchon and then lifted him off the ground. The man said Aubuchon stabbed him in the back when they fell, and that other men started to attack him, according to the report.
The man told the deputy he was able to get away from Aubuchon and the other men and ran away. The man also said a friend later picked him up and was driving him to a hospital when he was contacted by the police, the report said.
The man said someone told him Aubuchon was the person he was fighting with at the party, and he found pictures on social media of Aubuchon wearing the same sweatshirt that he wore at the party, according to the report.
The deputy reviewed Aubuchon’s social media page, and Aubuchon allegedly told someone through social media that the other man had threatened him with a gun and then jumped him, the report said.
“This investigation represents the excellent work done by Sheriff’s Office investigators, who often dedicate multiple weeks to a single case,” Sheriff Dave Marshak said in a statement. “Deputies and detectives continue to embrace advancing technology and the techniques necessary to leverage it as a powerful crime-fighting tool.”
