About 7,000 years ago, the bodies of nine brutally murdered people were dumped into a mass grave on the edge of an ancient farming settlement. While their identities will never be known, one thing is certain: These nine individuals were interlopers — possibly failed raiders or POWs — who met violent ends, a new study finds.
These people aren't the only early Neolithic victims whose lives ended in violence. But several factors set this newfound burial — found during a construction project in Halberstadt, Germany, in 2013 — apart from other mass graves dating to the same period, the researchers said.
For starters, these victims weren't local, but "outsiders with currently unknown origins," said study lead researcher Christian Meyer, an archeologist who researched the burial while working at the State Office for Heritage Management and Archaeology of Saxony-Anhalt, in Germany.

The "outsider" discovery was made thanks to an anaylsis of certain isotopes (a variation of an element that has a different number of neutrons in its nucleus) in people's bones and teeth that are determined by their diets. The analysis revealed that the victims in the mass grave had different isotopes in their remains compared with other people buried in the settlement, the researchers said.
In addition, the newfound grave contained only adults — eight men and one woman — but no children, which is unusual for Neolithic mass graves, Meyer said. For instance, another early Neolithic mass grave in Germany, known as Schöneck-Kilianstädten, had 26 victims, which included 13 children and 11 men and two women, Live Science previously reported.
Moreover, these young adults' injuries clustered at the back of the head, meaning the victims were likely hit with "blunt force" from behind, Meyer said.
"At other sites, where [other] chaotic massacres occurred, injuries are usually spread out over all areas of the skulls," Meyer told Live Science in an email. "Some of the injuries [at Halberstadt] also appear quite similar in size and shape, so overall one can assume a rather controlled application of lethal violence."
He noted that during the early Neolithic, the Halberstadt settlement belonged to the Linearbandkeramik (LBK), the first farming culture in Central Europe that planted crops and raised livestock. The settlement also contained traces of six LBK longhouses and regular burials, most of which hold just one person and LBK artifacts.
"The mass grave differs greatly from these regular, individual graves, as the bodies were just dumped into the mass grave pit and were not carefully arranged." Meyer said.
What happened?
Based on the evidence, it appears that "a group of non-local younger men [were] killed in a controlled manner" like executed prisoners, Meyer said.
At least two scenarios are possible: Either the victims were captured nearby (possibly as part of a failed raiding party) or they were brought in from farther away as POWs, Meyer said.
"We don't really know the answer," he said. But given that there's no evidence that LBK men were captured as POWs, it seems more likely that the victims were apprehended during a raid or farther away from the settlement, Meyer said.
"Likely they were LBK farmers as well, but from another area," he said. [In Images: Deformed Skulls and Stone Age Tombs from France]
The massacre suggests that this settlement had heightened conflict and social pressures that led to this violence, said Meaghan Dyer, a doctoral candidate in the School of History, Classics and Archaeology at the University of Edinburgh who was not involved in the study.
"This site provides a clearly differing pattern to other known massacres, representing a previously unknown practice of large-scale, male-targeted execution," Dyer told Live Science. "[It sheds] new light on interpersonal violence during a very key point in human prehistory."
The study was published online June 25 in the journal Nature Communications.
