JEFFERSON, Iowa [KCCI] — A Jefferson man accused of kidnapping his son will undergo a psychiatric evaluation. On Monday, a judge ruled that there was probable cause to suggest that 34-year-old Brandon Duong is not competent to stand trial.

Duong is charged with second-degree kidnapping and violating a custodial order after he removed his 7-year-old son from Greene County Elementary in January, prompting an Amber Alert. After a chase and hours-long stand-off, Duong surrendered and was taken into custody in northwest Iowa. His son was unharmed.

The case will remain on hold until the psychiatric evaluation comes back.
