The team led by Christina Grimmie, the former contestant on “The Voice” and YouTube star who was shot dead last week, has won the $250,000 grand prize for the Humane Society of the United States in a “social giving” charity event.

The Charity Champions League competition, launched earlier this month by CBS’s EcoMedia, featured 10 other celebs who led teams in support of various nonprofit orgs.

Grimmie, a finalist on season six of NBC’s “The Voice,” was killed after performing at a concert in Orlando, Fla. She was 22.

In honor of the slain singer, the Humane Society is creating the Christina Grimmie Animal Medical Fund to provide veterinary attention and ongoing care for its most critical animal rescue cases. “We hope that the Grimmie family, and her worldwide fans, take some solace in knowing that her compassion for animals and people will live on through this life-saving program,” Wayne Pacelle, president and CEO of the Humane Society said in a statement.

One of Grimmie’s final tweets rallied her fans to participate in the charity event:

The free-to-play charity competition awarded points to each team when members read, watched or shared content on the Charity Champions League website and recruited others to join their team, allowing them to support causes without making a personal donation. The event ran from June 1-15.

“Christina Grimmie and all our team captains proved that when you present the American public with an easy way to get involved and make a difference, they will take action,” said Paul Polizzotto, founder and president of CBS EcoMedia. “We are delighted to be able to direct critical funding to the Humane Society of the United States, which Christina was so dedicated to supporting, and to the other ten very worthy nonprofit organizations that participated in the competition.”

The prize amounts awarded in the Charity Champions League were: Nancy O’Dell for ALS.net ($100,000); Kevin Frazier for School on Wheels ($75,000); Cal Ripken, Jr. for Cal Ripken Sr. Foundation ($50,000); Phil Keoghan for National Multiple Sclerosis Society ($25,000); Weylie Hoang for ASPCA ($15,000); Usain Bolt for After–School All–Stars ($10,000); Mark Teixeira for Harlem RBI ($10,000); Jerod Mayo for Boston Medical Center ($5,000); YouTube creator Nika Erculj for the Trevor Project ($5,000); and Stephanie May and Matilda Donovan for Ronald McDonald House Charities ($5,000).

The $550,000 prize pool for Charity Champions League was provided through contributions from Toyota dealers, ServiceMaster, Tri-State Chevy Dealers, Winthrop University Hospital and Jerome’s Furniture.

EcoMedia, which lets marketers direct a portion of their ad budgets to participating nonprofit charities, was founded in 2001 and acquired by CBS in 2010.
