Community members appeal for help in locating missing woman in Thunder Bay, Ont.

A ground search is being organized in Thunder Bay, Ont., for a missing woman from Sandy Lake First Nation, according to community members.

Deborah Anishinabie was last seen in the early morning hours Thursday on the 100-block of Simpson Street, located on the south side of town, police say.

She's described as a 42-year-old Indigenous woman who's five-foot-one. She has long black hair, brown eyes, along with a star tattoo on her left shoulder and several smaller tattoos on both arms.

The Thunder Bay Police Service (TBPS) first posted about her disappearance on Saturday afternoon. Her first name was previously spelled as Debra, and age listed as 41, but that has since been corrected.

"Since the missing person report was received, officers have been working to gather as much information as possible and follow leads. Investigators have spoken to potential witnesses, spoken to people known to the missing individual, patrolled areas known to be familiar to the missing individual, and canvassed for surveillance footage," said Matt Vis, media relations co-ordinator with the TBPS, in an email to CBC News on Monday.

"Investigators remain in contact with family members and are keeping them updated as the investigation continues."

People on social media have made dozens of posts appealing for information about Anishinabie's whereabouts.

"One of our relatives from Sandy Lake is missing here in Thunder Bay," wrote Nishnawbe Aski Nation's Grand Chief Alvin Fiddler on Facebook. "If anyone has any information that may lead to her being found, please call the authorities. Her family is anxious to have her back home."

The Oshki-Pimache-O-Win Education and Training Institute also took to Facebook to share information about Anishinabie.

"We are deeply concerned for the safety of [Deborah] Anishinabie, a recent graduate of Oshki-Wenjack, who has been reported missing," the institute wrote. "Let's all come together to help bring [Deborah] home safely."

A community member told CBC News in a Facebook message that a ground search was being organized in Thunder Bay on Monday afternoon.
