"I am really sorry to report that we have now received news that Shani Nicole Louk has been confirmed murdered and dead," Israeli President Isaac Herzog told Germany's Bild newspaper.
Louk, 23, was one of scores of people taken by Hamas during a deadly assault on the Israeli military and civilian communities that killed 1,400 people, mostly civilians.
German Chancellor Olaf Scholz, whose government has staunchly supported Israel as it mounted an offensive against Gaza in retaliation, said Hamas had to be held accountable.
A family source told Reuters that a part of a body had been found which was matched to Louk's DNA.
"At least she didn't suffer," her mother Ricarda Louk told RTL/ntv.
