Watch: Woman consoles officer following Iowa ambush

URBANDALE, Iowa (CNN) An emotional scene played out in Urbandale, Iowa Wednesday following an apparent ambush where two police officers were killed. A woman was caught on camera consoling a police officer by offering him bottled water. The woman and the officer were both brought to tears.

Police have confirmed that weeks before Scott Michael Greene was apprehended as a suspect in the killings of the two Des Moines area police officers, he was removed from a high school football game because he displayed a Confederate flag during the national anthem.

Urbandale Police Chief Ross McCarty told reporters that Urbandale officers removed Greene from the football game. McCarty says some spectators complained after Greene waved the flag in front of spectators who are minorities.
