Victims of the Colorado Springs Shooting

KKTV reported that the recent shooting in Colorado Springs happened inside the Canterbury Manufactured Home Community on the east side of the city. Authorities responded at the scene around 12:18 a.m., May 9, following a report of the incident in the 2800 block of Preakness Way.

"Today we find ourselves mourning the loss of lives and praying solemnly for those who were injured and those who lost family members," said Colorado Springs Mayor John Suthers labeling the incident as a "senseless act of violence on Sunday morning." Suthers also sought the public's patience and the media's sensitivity while the authorities complete a "thorough" investigation.
