A traffic stop on U.S. highway 36 in Caldwell County wound up shutting down the highway after the driver threatened to kill himself.

In a news release, the Missouri State Highway Patrol said a Caldwell County Sheriff’s Department deputy pulled over the motorist for speeding approximately two miles east of Hamilton, Mo. After the vehicle was stopped, officials say the driver brandished a weapon and threatened suicide.

The Sheriff’s Office requested assistance from the Missouri State Highway Patrol.

Officials say U.S. 36 was closed in both directions as negotiations with the suspect began. At approximately 10:16 a.m. negotiations were successful, and the suspect agreed to exit the vehicle. The 39-year-old man from Hannibal, Missouri was taken into custody by the Caldwell County Sheriff’s Department.

The highway has since reopened for normal use.
