Hannah Kobayashi’s family is offering refunds to the hundreds of people who helped raise nearly $50,000 in their search for her after news that she was found in Mexico about a month after she disappeared, according to police referred to as voluntary disappearance.

“We are closing donations and any donor who would like a refund can submit a request by December 18th and it will be considered,” Sydni Kobayashi, Hannah’s sister, wrote in an update about the family’s fundraising effort, which includes their efforts, Finding them helps.

Hannah was reported missing in Los Angeles on November 11 after she failed to board a connecting flight to New York City.

The 30-year-old woman from Hawaii had traveled from Maui but, according to her family, behaved out of character before contact was lost.

Her missing person case attracted widespread media attention, driven by her relatives who said they feared she was a victim of kidnapping or human trafficking.

L.A. police later determined that Hannah had voluntarily traveled to the southern border on Nov. 12 and gone to Tijuana alone, with no evidence of foul play or crime.

Hannah’s relatives initially disagreed with this view and said they would continue their own search.

Money raised through GoFundMe will be used for transportation, search and rescue operations, temporary housing and to support a public awareness campaign, the family said.

It also provided some resources to deal with another tragedy: Hannah’s father, Ryan Kobayashi, died by suicide in LA last month while searching for her.

“This family was more than happy with their intentions and their spending. Everything has receipts,” Sara Azari, an attorney who works with Hannah’s sister and mother Brandi Yee, previously told PEOPLE.

“This is a very, very strange situation and they (Hannah’s family) deserve answers and closure,” Azari said at the time.

Then on Wednesday, December 11, Sydni and Yee released a statement through Azari saying Hannah had been “found safe.”

“The last month has been an unimaginable ordeal for our family and we kindly ask for privacy as we take the time to heal and process everything we have been through,” they said.

“We would like to express our heartfelt thanks to everyone who has supported us during this difficult time. Your kindness and care meant a lot to us,” added Hannah’s sister and mother.

They provided no further information and their attorney said there would be no further statements.

Lt. Doug Oldfield, one of the investigators on Hannah’s case, told PEOPLE that they were separately informed by Hannah’s family that she had been found in Mexico, but he had no further information.
