ALTAMONT, Ore. —

UPDATE: The Klamath County Sheriff's Office (KCSO) has released more information about an armed standoff in Boyd Court on Tuesday.

Around 4:20 a.m. that morning, deputies learned of a man who had suffered multiple stab wounds in a fight with another man. The victim was taken to Sky Lakes Medical Center for treatment. Deputies do not know his current condition.

Investigators determined that a house at 7212 Boyd Court in Klamath Falls was where the assault likely happened, and they went to the home. When they got there, they found the suspect, 53-year-old Thomas Anderson, was inside.

At the scene, deputies learned that Anderson recently had been in possession of several handguns, and that there were other guns in the home as well.

Deputies said that as they tried to talk to Anderson, neighboring homes were evacuated. They also got arrest and search warrants before trying to get inside the Boyd Court home. A nearly 7-hour standoff ensued while multiple attempts were made to take Thomas Anderson into custody.

Members of the KCSO Special Response Team moved an armored vehicle into position and used "chemical agents" to eventually cause Thomas Anderson to surrender. KCSO also used two types of drones and a Jackson County Sheriff's Office tactical robot.

Thomas Anderson is currently being medically cleared before he is lodged in the Klamath County Detention Center.

INITIAL REPORT: A standoff that reportedly lasted more than eight hours in a neighborhood southeast of Klamath Falls finally came to an end on Tuesday evening, according to a Lieutenant with the Klamath County Sheriff's Office.

The standoff began after a man with a warrant out for his arrest barricaded himself inside of a house on Boyd Court near the Altamont neighborhood. Law enforcement reportedly arrived at the scene around 8:30 a.m.

The Sheriff's Office brought in an armored personnel vehicle, and emergency personnel from multiple other agencies responded throughout the day.

Late in the afternoon, law enforcement fired tear gas canisters into the home — forcing the suspect out and taking him into custody. The Lieutenant estimated that the standoff lasted between eight and nine hours.
