Ricarda Louk told German outlet Bild that there is no "evidence that Shani is alive but has a serious head injury and is in critical condition," according to the Daily Mail.
"You have to act quickly and get Shani out of the Gaza Strip!" she reportedly said in a message directed at German officials. "We shouldn’t argue about questions of jurisdiction now!"
Shani was one of the hundreds of partiers attending the Nova festival before Hamas swooped in and massacred an estimated 260 civilians.
According to her aunt, Orly Louk, Shani was a peace advocate as well as a conscientious objector to military service. Shani had objected to joining the military due to her pacifist views, says Orly.
Shani's mother posted a video in which she begged for an answer on what has happened to her daughter.
"This morning my daughter, Shani Nicole Louk, a German citizen, was kidnapped with a group of tourists in southern Israel by Palestinian Hamas," she said in a video posted on Sunday.
"We were sent a video in which I could clearly see our daughter unconscious in the car with the Palestinians and them driving around the Gaza Strip."
"I ask you to send us any help or any news. Thank you very much."
Shani's family said that a bank has caught wind of her credit card being used in Gaza.
This news comes as reports reveal a stunning death toll of over 900 people in Israel since the Hamas attacks that began over the weekend.
Pro-Hamas demonstrations have been seen throughout the world ever since the carnage began.
