The suspect accused of fatally stabbing a Wausau native in a random knife attack has been found not competent to stand trial.

Ben Christianson, a 1988 Wausau East High School graduate who grew up on Wausau’s southeast side, was killed Aug. 27, 2019 while collecting soil samples in Greenfield as an employee of Ramaker & Associates. Christianson’s parents, Don and Jane, are well-known retired educators in the Wausau School District.

Amando Lang, a 20-year-old Greenfield man, faces intentional homicide charges in Christianson’s death, which followed months of violent behavior and potential mental health issues observed by neighbors and family members,” the Journal/Sentinel reports.

Lang’s case is now suspended after a hearing this month in Milwaukee County Circuit Court, during which a judge reviewed reports by doctors. Ultimately, Circuit Judge David Borowski found Lang not competent and unlikely to regain competency.

Borowski then converted the proceedings to a civil commitment without an objection from counsel and Lang was ordered to remain in custody at Mendota Mental Health under a chapter 51 commitment, though the length of his commitment is unclear at this time. He has been held at Mendota since October.
