TOPEKA, Kan. (AP) — An attorney for the family of a black Kansas man fatally shot by police says family members believe officers violated his constitutional rights and did not need to use deadly force.

In an interview Thursday, attorney Gillian Cassell-Stiga also said police body camera footage shows that 30-year-old Dominique White was “clearly trying to run away” when two Topeka officers shot him Sept. 28 near a park.

Cassell-Stiga also disputed the local prosecutor’s claim in his report that the footage shows White reached toward a gun in a pocket just before officers shot him.

Shawnee County District Attorney Mike Kagay announced Wednesday that he would not file criminal charges against the officers. He declared their use of force reasonable and showed reporters body camera footage.

Topeka police have launched an internal investigation.
