On June 22, 1882, Marshal Brown was killed by cowboys Steve and Jess Green in the Red Light Saloon as Brown and a deputy answered a disturbance call. With the help of the saloon employees the Green brothers escaped into Indian Territory, only to be caught in a gunfight with Territory lawmen in October. Steve Green and a deputy sheriff were killed and Jess Green was captured, riddled with 13 gunshot wounds. The Kansas governor gladly paid the Texas posse the $1,000 in Kansas reward money.

        Following an obviously uncomfortable wagon ride from Wise County, Texas, Jess Green died on November 5th in the county jail in Wellington, just prior to his murder trial. As a sign of respect, Main Street closed during the marshal's funeral, an event unheard of during the cowtown period. The marshal's grave in located in the city cemetery, Section 3, Lot 108.
