Abstract

fetched live from OpenAlex

Two females, Denean Worms and Brenda Hughes, were murdered in separate events in Cranbrook, British Columbia in 1984 within three months of each other. Terrence Wayne Burlingham was found guilty of both murders and he appealed. The Supreme Court of Canada granted Burlingham a new trial in the Worms case, but no evidence from Burlingham's confession nor the murder weapon could be used. The Crown counsel requested an evaluation of the two murders to determine if they were committed by the same person. The analyses of those murders revealed that they were linked by a personal "signature" of the killer. The murder cases reported here demonstrate a control-oriented signature. The killer used a .410 shotgun as his method of control and death, engaged in overkill of each victim by shooting them twice in the head, and left the victims in sexually degrading positions. Another signature feature was the absence of typical wounds to the victims which would be expected from a serial sex offender. All of these characteristics, in combination, accounted for this killer's personal expression.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
