# The Monster of Florence (1968): A Forensic Astrology Case Study



A live demonstration with the 1968 Signa case (Monster of Florence series)

> **TL;DR:** Our app lets you (1) package a case's timestamp + location to cast a forensic event chart, (2) auto-extract structured signals (rulers, houses, fixed stars, dominants), and (3) send a concise data bundle to AI for narrative analysis - then compare your chart-derived read to the historical record for bias checks.




## What Is Forensic Astrology?



Forensic astrology is a specialized application of astrology that analyzes **event charts** - horoscopes cast for the exact time and place of a crime, disappearance, or mysterious occurrence - to study how traditional symbolism describes the event and the people involved. For the full definition, history, and ethics, see [What Is Forensic Astrology?](/blog/posts/what-is-forensic-astrology)




Unlike traditional astrology focused on personal horoscopes, forensic astrology treats the *event* as the subject. Practitioners examine who/what/where/when signatures in a precisely timed chart, focusing on:




- **Angles and rulers** to identify key actors (victim, perpetrator, witnesses)

- **House emphasis** to understand context and setting

- **Planetary dominants** for behavioral profiles and motivations

- **Fixed-star overlays** for additional symbolic detail

- **Directional vectors** for search strategy and discovery zones




It doesn't replace forensics or evidence; it **frames symbolic hypotheses** (e.g., discovery vectors, relationship distance, witness channels, deception indicators) that can be compared with the documented record of solved or historical cases.




**In our app:** you import or type a timestamp, address, and time zone; we do the rest - chart casting, signal extraction, and a structured, auditable summary you can hand to AI or use in your own analysis.




## What Our App Does (in 3 Steps)




### 1. Event Packaging (one click)



Paste time & place. We auto-detect TZ/DST, normalize to UTC, store lat/long, and save an audit trail of conversions. No manual ephemeris lookups, no guesswork on daylight saving.




### 2. Chart + Signal Extraction



We compute:




- ASC/MC and angle rulers

- House placements for all planets

- Major aspects and applying/separating orbs

- Fixed-star contacts within orb

- Dominant signatures (by dignity, angularity, aspect weight)

- Mute/voice sign flags for communication/deception analysis

- House-based "witness vectors" and directional cues



Output is a compact JSON + a human-readable card with color-coded role tags.




### 3. AI Narrative (yours, not ours)



You pass the extracted signals to AI in your preferred style (technical or educational). We don't interpret unless you ask; we keep a **separation of concerns** so your team can compare chart hypotheses to case facts and check for confirmation bias.




## Live Case Study: 1968 Signa Double Homicide (Monster of Florence Series)




### Event Package Used for the Chart



**Earliest reliable notification:** Thursday, 22 August 1968, 02:00 CEST (00:00 UTC)

**Address:** Casa De Felice (private residence), Via del Vingone 154/1, Sant'Angelo a Lecore, Campi Bisenzio (FI), Italy

**DST:** Yes (Europe/Rome, UTC+02:00)

**Support:** Six-year-old Natalino Mele reached a nearby house around 02:00; De Felice residence is attested in records tied to Via del Vingone 154.




### What the Historical Record Says (Brief)



A couple was shot in a car on a rural lane near Signa after visiting a local cinema. The six-year-old child reached the De Felice residence at approximately 02:00. The 1968 case was later ballistically linked (in 1982) to the "Monster of Florence" series via archived shells and bullets, transforming it from a single domestic incident into the first known attack in Italy's most notorious serial case.




### The Chart-Derived Read vs. Documented Events








Chart Signal (App Output) 
Documented Event 
Fit 
Notes 




Cancer ASC; family/home entry point 
Discovery via private home (De Felice) ~02:00 
**High** 
Residence/family doorway as the first reliable timestamp 


Moon (ruler) in Leo H2 - valuables/vehicle trigger-field 
Victims in a car on a secluded lane 
**Med - High** 
H2 mapping to vehicle/possessions/self-value fits the scene 


3rd-house emphasis - short trips/local routes 
Local cinema - rural track - nearby house on foot 
**High** 
Strong local-mobility chain that night 


Perp style dominated by Mercury (youthful/small; research/surveillance) 
Official conviction: spouse Stefano Mele; later theories emphasize perimeter watchers 
**Mixed** 
Diverges from "spouse-did-it" model; rhymes with later stalking/surveillance narratives 


Perp ruler in H11 - outer-circle / acquaintance 
Verdict (1970 - 73): intimate partner; later ballistic linkage clouds that 
**Low - Med** 
Chart's social-peripheral tone conflicts with verdict but aligns with later re-framing 


Witness vectors: Mercury in H4; Sun in H3 
Doorway/home witness (De Felice) + neighbors/local routes 
**High** 
Matches the discovery and locality dynamics 


Deception config: mute angles - silence/omission 
Confession - retraction - confession cycles; contradictions 
**Med - High** 
Known reversals and testimonial ambiguity 


Outcome: IC Virgo; 4th-ruler Mercury in H4; H4 Jupiter & Venus - "procedural/records decide" 
Procedural conviction; later archival ballistics (1982) reshape the case's status 
**High** 
Exactly "paperwork/archives/technicalities decide" twice over 







## Positioning This Feature




### Evidence-adjacent, not evidence-of



You keep a clean separation: chart signals help **prioritize lines of inquiry**; facts and documents confirm or refute. The app doesn't tell you whodunit - it tells you *where to look next* and *what patterns to test*.




### Bias Controls Built-In



Side-by-side **Chart vs. Record** view encourages *falsification* rather than confirmation bias. You see what fits, what doesn't, and where the chart's symbolic language diverges from known outcomes - so you can calibrate how much confidence the method deserves.




### Auditability



Every conversion (TZ/DST/coordinates) and every chart flag is logged and exportable. Colleagues can reproduce your chart, verify the math, and critique the interpretation - essential for team-based or archival work.




## Ethical & Legal Notes



> Forensic astrology is an **exploratory framework**. It must not substitute for police work, legal standards, or clinical judgment. Use responsibly; do not dox or harass individuals. Always cross-check chart hypotheses with verified evidence, timelines, and documentation.

## Try It Yourself



Our [Forensic Dashboard](/features) is built into Vox Stella. Cast an event chart, extract the signals, export to JSON, and run your own validation studies against documented cases. It is a research and teaching tool, not a way to direct real investigations.
