Decapitation murder suspect pleads guilty but insane
Lawyers for Joshua Webb, accused of killing his mother Tina Webb and stabbing Estacada Harvest Market employee Mike Wagner while carrying his mother's severed head into the store last May, have filed a notice with the Clackamas County Courthouse stating that he will plead guilty but insane.
Webb's attorney Maryann Meaney filed documents on Friday, Feb. 23, indicating Webb would use the defense.
"(The) defendant will be relying on the defense of guilty except for insanity in that as a result of mental disease or defect at the time of engaging in criminal conduct," Meaney wrote in a court document. "(The) defendant lacked the substantial capacity either to appreciate the criminality of his conduct or to confirm his conduct to the requirements of law."
Webb's trial is scheduled to begin next summer.
He faces charges of murder, attempted murder, first-deggree assault, first-degree abuse of a corpse and first-degree aggravated animal abuse.
Last May, in the Colton home he shared with his parents, Webb allegedly killed his mother, Tina Webb. He is accused of then dismembering her body by cutting off her head. A short time later, he allegedly entered Harvest Market in Estacada, "covered in blood," holding "a knife and what looked like a human head," according to police reports.
Inside the store, he is said to have stabbed Wagner and was restrained by employees until law enforcement reached the scene.
Webb faces charges of attempted murder and assault for the incident at Harvest Market.
Responders also found a dead dog at the Webb residence in Colton, for which Webb is also being charged.
A search for former criminal offenses committed by Webb unearthed a Class C violation for unlawful use of metal objects on tires 17 years ago. Webb pleaded guilty and paid a $70 fine.
Wagner was released from Legacy Emanuel Medical Center in North Portland a week after the incident. In an interview a month later, he told the Estacada News that he was "looking forward to finishing up the healing process."
Estacada community members rallied around Wagner in a variety of ways, including a charitable donation account at U.S. Bank and numerous signs, flowers and cards at Harvest Market and other locations around town.
Several months after the incident, Mayor Sean Drinkwine signed a proclamation honoring Wagner's fellow Estacada Harvest Market employees for their acts of courage and heroism during the incident.
