The Los Angeles Times noted that two separate pages on the fundraising site GoFundMe, "Support Officer Darren Wilson" and "Support Officer Wilson," appeared to stop taking donations at about the same time Saturday.
The pages had raised $235,550 and $197,620 for Wilson, respectively.
The "Support Officer Wilson" page was run by a St. Louis-based police charity, Shield of Hope, which listed a spokesman for the Ferguson Police Department among its officers on its state nonprofit records, according to the Times. The newspaper was unable to reach the three officers listed for more information about their fundraising effort.
There was even less information available about who was the founder behind the "Support Officer Darren Wilson" page, but GoFundMe told the newspaper that it could vouch for the anonymous operator.
A Facebook page connected to the fundraising efforts said Sunday that the decision to shut down the fundraisers was "made by those closest to Officer Darren Wilson looking out for his best interest." The post assured supporters that previous GoFundMe donations would still go to Wilson.
After Wilson was identified as the officer who fatally shot 18-year-old Michael Brown on Aug. 9, counter-protests sprung up in support of the officer. A fringe Ku Klux Klan group in South Carolina also began collecting donations for Wilson, even though a leader of of the white supremacist group condemned the effort.
