The presence of raspberry seeds in her stomach contents, coupled with an estimated age of early to mid-twenties at death, led to her being nicknamed Hallonflickan (Swedish: [ˈhalɔnflɪkːˌan] ⓘ; lit.

Axel Bagge, an archaeologist who collaborated on the initial examination of her remains, hypothesised that she had been deliberately drowned, either as a human sacrifice or as the victim of a witch execution.

[1][8] In response, the Board dispatched geologist and archaeologist Karl Esaias Sahlström [sv; no], along with palynologist Carl Larsson, both from the Geological Survey of Sweden.

[9]: 248–249  Upon arrival, they observed that the skeleton was in an upright position, with the detached skull rolled in such a manner that the chin and foramen magnum were oriented directly upwards.

The block was placed on a Masonite board and, along with several loose bones found in the bog, was transported by train to the Swedish History Museum in Stockholm in a wooden box.

[2]: 101 Three years prior to this discovery, a flint arrowhead had been unearthed in the same bog, approximately 6 m (20 ft) north of the skeleton's location and at an equivalent depth.

[9]: 248–249 [11] A more comprehensive physical anthropological investigation was conducted by Sahlström, osteologist Nils-Gustaf Gejvall [sv], and anatomist Carl-Herman Hjortsjö; their findings, including a detailed description of the remains, were published in 1952.

As of 2017[update], radiocarbon dating had been employed on the skeleton three times: the first two analyses corroborated the pollen analysis result, whilst the third, conducted using accelerator mass spectrometry in 2015, yielded a range of 3928–3651 BC.

He referenced Dahr's study of remains from a Stone Age settlement on Gotland, Sweden's largest island, where the average female height was estimated at 153 cm (5 ft 0 in)—a figure Gejvall considered distinctly short—as a point of comparison.

[12] Analysis of strontium and oxygen isotope ratios in the tooth enamel from one of the Luttra Woman's molars indicated that she likely originated from present-day Scania, the southernmost region of Sweden, before relocating to the Falbygden area later in life.

[1] The skull exhibited a perforation below the left eye socket, likely resulting from a chronic bone infection; otherwise, her remains bore no traces of injuries or diseases.

[9]: 248–249  Sahlström noted that the skull's imprint on the peat block suggested a prone position; Dahr concurred, concluding she had been lying face down.

[1][5] To create the bust of the Luttra Woman, Nilsson arranged for her skull to be CT scanned at the Karolinska Institute, a research-focused medical university in Stockholm.

He shaped her face accordingly, incorporating a narrow nasal bridge, which resulted in what he described as "a fully modern appearance", rather than the stereotypical visage of a Stone Age woman.
