The Serial Killer Who Married 20+ Women : Cyanide Mohan Case

Overview

The video narrates the origins, method, and investigation of the “Cyanide Mohan” case, describing Mohan Kumar Vivekananda as a serial killer who allegedly killed 20+ women.

How Mohan initially gained trust (especially with lower-income women)

• 2009: A woman named Pushpa (25) begins a romance with “Mohan” after he approaches her and presents himself as an attractive, credible government teacher.
• He gains the confidence of her family, and Pushpa’s family accepts marriage without dowry, creating a “dream” scenario for them.
• Pushpa later disappears after traveling alone with him under the pretense of a temple visit/romantic trip.
• Her case initially leaves investigators unable to find her or him.

The pattern behind his marriages and manipulation

The video portrays Mohan as someone who:

• Enters relationships with women (often involving student dynamics earlier in his teaching career)
• Uses romantic promises of marriage and dowry-free weddings
• Relies on secrecy, changing identities, and isolating victims from their families by taking them to other locations/lodges

His background is described as coming from a Hindu Dalit family and rising through education and a government-teaching pathway. The video further alleges:

• Multiple secret relationships and marriages
• Religious/cultural conflicts (e.g., with Mary, described as Christian)
• Infidelity and increasing misconduct in his professional life

To sustain a double life and fund his lifestyle, the video alleges he committed fraud using fake signatures/stamps and manipulated loans/salary documentation.

Escalation into murder using cyanide

After an earlier legal incident (the Ratna case) where Mohan is portrayed as being acquitted due to changing testimony, the video claims he grew bolder.

The killing method is described as:

• Targeting unmarried women from lower economic backgrounds (families allegedly desperate for marriage and less able to navigate or afford investigations)
• Administering cyanide disguised as contraceptive pills/sedatives
• Robbing victims of jewelry/valuables and then disappearing

The video claims Mohan learned cyanide-related knowledge while in jail (from another inmate/goldsmith) and then built a “system” to reduce detection risk.

Cited victims and incidents

• Vanitha (2004): Allegedly killed quickly after taking “contraceptive” pills at a lodge/area; her body reportedly dismissed/ignored by police.
• Ganga Maa (2003): An attempted theft/assault using sleeping pills; later complaints lead to a repayment deal to avoid charges.
• Anitha Mulayam (2009): Described as the final major case that triggered a broader breakthrough.

Why police attention finally intensified (Anitha’s case and mismanagement)

When Anitha disappears, the video claims political and social pressure shapes the narrative, including right-wing groups pushing a “love jihad” framing.

It also alleges police mishandled jurisdictional links:

• The missing complaint came from one area
• The body was found in another
• This delayed recognition that the cases were connected

Inspector K N Gobra is described as working under public pressure, initially searching for witnesses/clues using call details. Eventually, the investigation finds connections between missing women via phone/call records, suggesting Mohan reused victims’ digital identities (such as phones/SIM cards).

The breakthrough: tracing IMEI and building a sting

• Since SIM tracing is described as unreliable (the video claims SIM swapping),
• Investigators shift to tracking IMEI numbers.
• This reportedly identifies a phone connected to Mohan, described as a government teacher with a hidden criminal identity.

A sting is then set using Sumitra, a survivor targeted earlier. The video claims:

• She refuses/doesn’t fall for Mohan’s pill trick due to using protection previously
• Mohan adapts and becomes predictable
• Police ambush him when he arrives to meet Sumitra
• He is arrested

After arrest: estimated kill count and courtroom outcome

The video claims raids at Mohon’s home turned up stolen jewelry, fake documents, and cyanide. Interrogation is portrayed as chilling and evasive, with Mohan allegedly unable/unwilling to provide names while describing intimate details.

The police reportedly conclude:

• At least 33 women may have been killed
• But only 20 murders could be more clearly supported with testimony/evidence

In court, Mohan is depicted as disputing forensic interpretation and witness credibility—such as claiming it was insecticide rather than cyanide, and challenging witness statements.

Conviction basis (as depicted in the video)

The conviction is attributed to:

• A survivor confirming he gave pills, but she didn’t consume them
• A temple priest witness connected to events around Anitha

He is finally convicted and sentenced to life imprisonment (as referenced by the video).

Core conclusion of the video

The video frames the case as “new-age” serial killing—combining:

• Romance/identity manipulation
• Financial fraud
• Exploitation of social vulnerabilities
• Cyanide poisoning

It also highlights an investigative breakthrough (described as IMEI tracing + a sting) that overcame earlier police inaction and fragmented reporting.
