How cases like this get solved
Not by a crowd naming a suspect. In every case below, the break came from one of four things: a survivor, preserved evidence, a specific observation given to the police, or routine policing. Here is what each looked like and what the public's part was. At the bottom: which of those paths are open in this case.
South Africa
The Nasrec killer: Lazarus Mazingane (16 murders, 22 rapes)
Johannesburg, late 1990s; arrested 2000- How it broke
- A woman whose tyre had been deflated by a rock placed in the road called for help, was attacked, escaped, and identified him to police. Detective Piet Byleveld recognised the method from the Nasrec series and had DNA compared at the Pretoria forensic laboratory. It matched.
- The public's part
- A survivor went to the police. Everything else followed from that.
- Lesson here
- Near-misses solve series. If you got away from someone in this area, that is the single most valuable thing you can tell the task team.
The Phoenix Strangler: Sipho Thwala (16 murders, 10 rapes)
Phoenix, KwaZulu-Natal, 1996–97- How it broke
- He burned the sugar-cane fields where he left his victims to destroy evidence. One body was found before the field burned. DNA from the scene matched a sample police had taken from him in 1994, when he was arrested for a rape and acquitted.
- The public's part
- Someone found and reported a body in time. The match came from a database.
- Lesson here
- Evidence beats eyewitnesses. South Africa's DNA database exists for exactly this; the public's job is to keep scenes and footage intact.
The ABC killer: Moses Sithole (38 murders)
Atteridgeville, Boksburg, Cleveland, 1994–95- How it broke
- He phoned journalist Tamsen de Beer at The Star, claimed the murders and gave directions to a body to prove it. The calls were traced; police cornered him; he attacked a constable with a hatchet and was shot and arrested. De Beer's testimony was central at trial.
- The public's part
- A journalist kept him talking and handed everything to the police, she did not investigate him herself.
- Lesson here
- Contact with the media goes to the police, verbatim, immediately. That is the model for this site, too.
The West End killer: Jack Mogale (16 murders, 19 rapes)
Westonaria, 2008–09- How it broke
- Police were given his car registration number after a teenager went missing. The SAPS Investigative Psychology Unit had already linked the cases by method, victimology and location; the vehicle turned a linked series into a named suspect.
- The public's part
- Somebody noticed a vehicle and gave the number to the police, not to a WhatsApp group.
- Lesson here
- A number plate, a time and a place, given to SAPS, is worth more than a thousand online theories.
Elsewhere in the world (4 cases)
The Long Island serial killer: Rex Heuermann (charged 2023)
Gilgo Beach, New York, 2010–2023- How it broke
- In 2010 a witness described a first-generation Chevrolet Avalanche seen with one of the victims. Thirteen years later a new task force ran that description against vehicle records, then used cellphone location data and DNA from discarded items to build the case.
- The public's part
- One witness, one vehicle description, given to the police and kept on file.
- Lesson here
- Tips do not expire. Give it to the police even if you think it is small or old.
The Golden State Killer: Joseph DeAngelo (arrested 2018)
California, 1974–86- How it broke
- Crime-scene DNA was compared with public genetic-genealogy databases to find distant relatives, and investigators worked down the family tree to one man, then confirmed with a discarded DNA sample.
- The public's part
- None directly, decades of preserved evidence and a lawful investigative technique.
- Lesson here
- Preserved evidence outlives everyone's memory. Footage you keep today may matter in a year.
BTK: Dennis Rader (arrested 2005)
Wichita, Kansas, 1974–91- How it broke
- He sent a floppy disk to a TV station; hidden document data on it named a church and a user. Police confirmed with DNA from a relative's medical sample.
- The public's part
- A TV station handed the disk to the police untouched.
- Lesson here
- Anything a perpetrator sends to the media is evidence, not content.
Ted Bundy, David Berkowitz, Peter Sutcliffe
USA and UK, 1970s–80s- How it broke
- A traffic stop (Bundy, twice), a parking ticket near a scene (Berkowitz), a routine police check of a car with false plates (Sutcliffe).
- The public's part
- Ordinary policing, sometimes prompted by a resident who noticed a car that did not belong.
- Lesson here
- Visible patrols and attentive residents catch people. Vigilantes do not.
What did not work, anywhere
- Crowds naming suspects. After the 2013 Boston Marathon bombing, online sleuths named an innocent missing student; his family was harassed while they searched for him. He was later found dead, unconnected to the attack. No crowd-sourced identification has ever solved a serial case; several have derailed one.
- Vigilante action. In South Africa, people have been killed by mobs on suspicion alone. Every one of those deaths is a second crime and a wrecked investigation.
- Psychics, profiles from news clippings, "I know who it is" posts. Zero cases. Ever.
So, in this case
- If someone tried to grab, follow, lure or offer you a lift in Rhodesfield, Kempton Park, Olifantsfontein or KwaThema since June: tell the task team. Survivors are how Mazingane and Mogale were caught.
- If you saw a vehicle or a person at a time and place that fits: tell the task team: plate, colour, time, direction. That is how the West End killer was caught.
- If you have footage: keep it and tell SAPS you have it. That is how cases get proved in court.
- If you want to help without any of the above: send sources, corrections and hazards, sign the petition, and refuse to share names.

Which paths are open in this case
Each path above is asked one question: is it open here, and what would open it further? This is about the structure of the case, never about a person. "What you can do" always goes to the police; "what we ask of the authorities" is what the petition and partners push for. Updated 2026-09-15.
1. A survivor of an attempt identifies the offender
Open, the public can move it
- Where it worked
- Nasrec (Mazingane, 2000) and West End (Mogale, 2009) were both broken by women who got away and went to the police.
- Why it applies here
- In South African series, approaches are often a lure or a sudden grab, and attempts fail. No public appeal for survivors has been made yet.
- What you can do
- If you or someone you know was followed, grabbed at, offered a lift or lured in Rhodesfield, along the R21, in Olifantsfontein or KwaThema since June, even if nothing happened, call the task team. Running clubs and women's organisations: ask your members.
- What we ask of the authorities
- A formal SAPS appeal for survivors of attempts since June.
2. A vehicle seen at the right time and place
Open, the public can move it
- Where it worked
- The West End killer was arrested after someone gave police a car registration; the Long Island case turned on a 2010 witness description of a pickup.
- Why it applies here
- Police said the Olifantsfontein woman may have been 'dumped', which implies a vehicle. The sites sit on a highway corridor.
- What you can do
- A vehicle stopped where nothing stops, on the R21 service roads, York Road or Main Road, Rhodesfield, at odd hours: colour, type, any part of the plate, the time. To the task team, not to a group.
- What we ask of the authorities
- Canvass hotel, logistics-yard and taxi-rank staff along the corridor; collect camera positions from security companies.
3. Exact times and places for the phone and cell-tower work only police can do
Open, the public can move it
- Where it worked
- Standard in South African prosecutions once investigators have an anchor time and place.
- Why it applies here
- Only one victim has a public last-seen time and place: an evening run on Main Road, Rhodesfield, 9 September. Many runners carry a GPS watch or a phone app.
- What you can do
- If Ms Moselakgomo's family or running club have a GPS track or phone-app record of her last run, it shows where movement stopped. Give it to the task team, and to nobody else.
- What we ask of the authorities
- Nothing public; this is theirs to run.
4. Identify every victim: her movements point to where she was taken
Open, the public can move it
- Where it worked
- Every solved series: knowing who she was tells you where she was, and who saw her last.
- Why it applies here
- At least one woman is unidentified; two more have not been publicly identified.
- What you can do
- Missing a woman from the East Rand since June? Report it and ask for the task team. Families recognise descriptions that databases don't.
- What we ask of the authorities
- Publish missing-person notices for the unidentified women; cross-check reports province-wide.
5. A relative or employer notices and calls
Open, the public can move it
- Where it worked
- The Unabomber was caught because his brother recognised his writing; many South African arrests follow a call from a relative.
- Why it applies here
- Nothing public suggests this has been tried. Someone employs, houses or loves the person police are looking for.
- What you can do
- Employers near the sites: preserve gate logs and footage for the discovery dates; report unexplained absences or injuries. Families: the anonymous line exists for you.
- What we ask of the authorities
- A direct appeal to employers along the R21 corridor.
6. Routine policing: patrols and stops at the right hours
Open, the public can move it
- Where it worked
- Bundy, Berkowitz and Sutcliffe were all caught by ordinary policing, sometimes after a resident reported a car that did not belong.
- Why it applies here
- The running community has asked for visible patrols and lighting; SAPS's own advice implies risk at running hours.
- What you can do
- Report a car that does not belong, at the time it is there. Join escorted groups rather than running alone.
- What we ask of the authorities
- Patrols on the R21 service roads and in Rhodesfield at dawn and dusk; a lighting audit (petition demand 4).
Paths that belong to the police, or are dormant (2)
DNA and behavioural linkage across the scenes
Police work, nothing for the public to do
- Where it worked
- Nasrec and Phoenix were proved by DNA; the West End series was linked by the SAPS Investigative Psychology Unit.
- Why it applies here
- The IPU is on the task team; DNA comparison (including with the July arrestee) is standard. Nothing here is public, and none of it needs the public.
- What you can do
- Keep scenes and footage intact. Nothing else.
- What we ask of the authorities
- Keep the task team and the IPU on the case until it is closed; prioritise forensic turnaround (petition demand 3).
Contact from a claimant to the media
Dormant, nothing to act on yet
- Where it worked
- The ABC killer was traced through his calls to a journalist at The Star; BTK through a disk he sent to a TV station.
- Why it applies here
- No such contact is known.
- What you can do
- Journalists and this site: anything received goes to SAPS untouched, immediately.
- What we ask of the authorities
- None.
