I am a volunteer researcher for the Texas Peace Officers Memorial. On 3 Dec 1878 Constable (also reported as deputy) Louis (may be Lewis) COOPER was shot and mortally wounded in Pattison in Waller County. John O. GREER shot and killed his uncle Ed. B. GREER and then shot COOPER. On 30 March 1882 Sheriff McDADE shot GREER and arrested him. I am seeking information about COOPER as to whether he died from the wounds, where he is buried and any surviving family members.
