Results of the strontium, carbon and nitrogen isotope analyses. Strontium isotope ratios of enamel (a) and carbon and nitrogen isotope data of bone collagen (b) of the individuals from the mass grave in comparison to data from regular LBK and likely LBK settlement burials at Halberstadt. Both analytical methods show the mass grave individuals to be different from the regular interments implying both non-local origins and distinct dietary habits. Individuals subsequently identified as non-LBK have been removed from the settlement burial dataset published previously⁴¹
