The peer-reviewed publication affiliated to this dataset has been published in Forensic Sci. 2021 an MDPI journal, and can be accessed here: https://doi.org/10.3390/forensicsci1020008. Please cite this when using the dataset. Usually, crimes and more specifically assassinations take part indoors and at particular locations. Under this scope, we demonstrate a range of 3D scanning modalities in a simulated indoor crime scene. We propose 3D scanning as a complement to traditional photographic documentation of the scene. For better comprehension of the reconstruction quality obtained from each modality and/or further research on the topic, we release the 3D files of the scene to the public. We also provide ground-truth measurements as a comparison to those that could be obtained using the 3D reconstructions. The modalities that were utilized are: FARO Focus M70 FARO Freestyle 3DX DSLR and Pix4D photogrammetry software RGB-D scanner based on Asus XTION iPhone 12 Pro Max and Trnio 3D Scanner application
