As expressions of support poured in from across the nation, with people holding peace rallies and candle light vigils in dozens of cities, Rao flew in from Washington to the tragedy struck the city in Wisconsin.
The Indian Ambassador also met the Oak Creek Mayor, Steve Scaffidi, besides officials from the Federal Bureau of Investigation and the local police who provided her a first-hand assessment of the ongoing investigation.
They briefed the Indian Ambassador on how the incident happened and the steps that are now being taken by the police and local administration for the protection of the Sikh community as well as the status of the investigation.
Later in the evening, she attended a community vigil held in honour of the shooting victims where she briefly addressed those attending the meet to honour those killed in the shooting incident.
She met the victims' families in Oak Creek including relatives of Satwant Singh Kaleka, the slain president of the Gurudwara, who confronted the shooter and helped save the lives of several worshippers.
In her meetings with the victims' families, Rao expressed her condolences and sympathies and offered all kinds of assistance on behalf of the Indian government.
"Struck by calm&composure of victim families. No trace of rancor. But their tears would fill an ocean, make it overflow," Rao tweeted after her meeting.
