The first page, “Support Officer Darren Wilson,” had raised the most concern because its creator was anonymous and had not received certified status from GoFundMe.

Missouri state Rep. Jeffrey Roorda, a Democrat who is helping to handle Wilson’s fundraising efforts, said the creator of that page is a teenage girl from the St. Louis area.

“I think she thought she’d raise a few hundred dollars, and she ended up raising a few hundred thousand dollars,” Roorda said in a phone interview Monday night. After her page got popular, Roorda said, the young woman started receiving “serious threats.”

Roorda said he doesn’t know how old she is or whether she’s a minor; he described her as a “teenage girl,” a “young girl.”
