Roll of Honor
Incident
Marshal Thadeaus Gillis was shot and killed as he remonstrated with two intoxicated men for using profane language in the Hyman Mercantile, on Robb Street, at about 1:30 pm.
As one of the men slapped him in the face, the other picked up a shotgun on a counter and shot him in the back of the head, causing instant death. Both were arrested, convicted of murder, and sentenced to life. The 25-year-old killer, from a prominent family, was pardoned by Governor James K. Vardaman on January 22, 1908.
Marshal Gillis was a Confederate Army veteran of the Civil War, having served with the 22nd Mississippi Infantry, Company E. In 1863 he was captured while carrying dispatches during the siege of Vicksburg. He had served with the Summit Police Department for 20 years.

I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.
Marshal Gillis gave the Summit Police Department 25 years.
Thank you for your service to the Summit community. Thank you for your service before it. Gone but never to be forgotten.
Rest easy, brother.
