A man was shot and killed Wednesday evening in Pittsburg, police said.

Dominique Thomas, 22, of Pittsburg was found shot in the head near the corner of West and West 11th streets about 7 p.m., said Pittsburg police Capt. Ron Raman. He died at the scene.

Officers found a “large uncooperative group gathered at the location, none of which were willing to come forward with any information relative to the shooting,” Raman said.

No arrest has been made.
