BELTON, Mo. — A standoff involving police and an armed suspect has ended that caused two schools in Belton, Missouri, to be put on lockdown Thursday afternoon.

The Belton Police Department tells FOX4 officers were involved in a standoff with an armed suspect three blocks away from Gladden Elementary School at Hargis Lane and Westover Road.

Gladden Elementary and Wilckens STEAM Academy at Hillcrest were put on lockdown as a precaution.

The school district said it modified dismissal for many of the schools as a precaution to keep students and staff safe.

Police said the incident started just before 1 p.m. as a domestic situation when a man told a woman that if she called police he would “shoot it out with them.”

The standoff ended just after 6 p.m., according to police. Police said the suspect shot himself and was taken to an area hospital where he was pronounced dead. He has not been identified at this time.
