Indian-origin techie Vishnu Irigireddy was among the three persons killed in a tragic climbing accident in Washington state’s North Cascades Range of western North America. Vishnu, 48, a resident of Seattle, was attempting to climb North Early Winters Spire area of the Cascades along with his three friends, Tim Nguyen, 63, Oleksander Martynenko, 36 and Anton Tselykh, 38, on Saturday when the accident happened.

The group noticed a storm coming and started to retreat when at some point during their descent, the team’s anchor point failed and sent the group plunging 200 feet down.
