AUSTIN (KXAN) — Police are searching for a second person who may be connected to an assault on a senior citizen during a protest in south Austin in November, police confirmed Thursday.

James Scott Saunders faces a third-degree felony injury to an elderly person charge. He is not in custody, but police connected him to the scene through video that appeared to show him and 32-year-old Benjamin Paul-Jordan Weir beating up a 68-year-old man.

Police say the victim had left an art exhibition in the 1600 block of Pleasant Valley Road to go refill his coffee cup at H-E-B. Members of the group “Defend Our Hoodz” were protesting the exhibition on Nov. 10. Saunders and Weir were among those protesting, Austin police said, and added that Weir had a megaphone and was shouting at the victim. The victim came away with a large knot to the back of his head, cuts on his hand and blood in his mouth.

Weir was arrested at the scene.

“Defend Our Hoodz” is an Austin-based protest group that advertises as being against neighborhood gentrification. According to the affidavit, they objected to having an art district on Riverside, and had tossed pamphlets at the scene.
