Just before 6 p.m., a group of men was gathered at the park when an armed individual walked up to them and shot someone in the group, killing them, the Sacramento County Sheriff’s Office said in a press conference Monday night.

That gunman ran from the scene towards an area just outside of Ventana Townhomes Complex when another armed person chased them down and shot them just a short distance away near the intersection of the aforementioned roadways.

CBS13 spoke to friends and family of both of the dream men, but they claim they do not know what started the shooting.
