Bengaluru triple murder: Why cops wanted to make AI chatbot an accomplice

Kenneth and Shwetha were in a live-in relationship and had plans of starting a cloud kitchen venture. (Image: File) New Delhi,UPDATED: Jul 22, 2026 11:09 IST Written By: Avinash Kateel Every crime has a mastermind. Every mastermind has a confidant. According to Bengaluru Police, Kenneth's confidant in the triple murder he committed was not another person. It was an AI chatbot. Kenneth (25) consulted the AI chatbot at almost every stage of planning for nearly six months, which he finally turned into reality on June 22 after allegedly killing the parents and younger sister of his live-in partner, Shwetha, in Bengaluru's KR Puram area on June 22, police sources told India Today TV.

  • Kenneth relied heavily on Google Gemini AI chatbot during six months of murder planning.

On the Limits of Sampling-Based Reachability: Geometry, Dynamics, and Sample Complexity

This paper investigates how the geometry of the initial set, dynamics, and sampling distribution affect the accuracy of sampling-based reachability analysis. By formulating the problem as geometric support estimation, the authors identify two regularity conditions—positive reach of the initial set's complement and Lipschitz continuity of the dynamics—that allow a probability-mass coverage guarantee to be upgraded to Hausdorff distance accuracy. The sample complexity scales exponentially with state dimension and time horizon, and this exponential dependence is intrinsic, not an artifact of the method. Experiments on nonlinear systems confirm that adversarial sampling improves constants but not the scaling.

  • Positive reach of the initial set's complement and Lipschitz continuity of the dynamics are key regularity conditions for converting probability coverage to geometric accuracy.
  • Sample complexity is $\tilde{\mathcal{O}}((e^{3LT}/r)^n)$, exponential in dimension and time.

STeP: Signal Temporal Logic for Precise Specifications for Action Generation with Vision Language Models

Vision-language-action (VLA) models show impressive generalization but often lack interpretability and struggle with precise natural language instructions involving spatial, temporal, and logical constraints. This paper proposes a hierarchical framework using Signal Temporal Logic (STL) as a shared representation between high-level language understanding and low-level robot execution. The high-level policy uses a VLM to decompose instructions into subtasks, generates STL specifications, and selects low-level policies. STL constraints are enforced via model-predictive control or monitored during execution. Evaluated on a real-world tabletop domain, the framework improves precision, reliability, and interpretability of language-conditioned robot planning.

  • Proposes using Signal Temporal Logic as a formal intermediate representation between VLA models and robot execution.
  • High-level policy decomposes instructions, generates STL specs, and selects low-level policies; low-level can use STL-guided MPC or monitoring.

Hazard or Anomaly? Evaluating VLMs for Understanding Dangers and Discrepancies

Vision-Language Models (VLMs) often confuse anomalies with hazards, as current binary safe/unsafe evaluations fail to differentiate true physical dangers from unusual scene elements. This research introduces an explicit hazard vs. anomaly distinction, evaluating multiple VLMs across datasets. Results show VLMs frequently misinterpret anomalousness as hazardous, relying on contextual irregularity as a proxy for danger. Separating the two provides more informative safety reasoning evaluations, exposing failure modes obscured by binary judgments. A public dataset is available on Roboflow.

  • Vision-Language Models (VLMs) often misclassify anomalies as hazards, over-relying on contextual irregularity.

Using Fine-Tuned LLMs to Identify Indicators of Vulnerability in UK Police Incident Logs

This study explores adapting an LLM classification pipeline, originally developed on US police data, to estimate the prevalence of four vulnerability indicators (mental ill health, substance misuse, alcohol dependence, homelessness) in UK police incident narratives. Analyzing nearly 3,000 de-identified logs, the research finds that LLMs can provide meaningful prevalence estimates at scale, but naive deployment is unreliable, requiring substantial human input and statistical correction. The study underscores that LLM outputs cannot be treated as valid measurements without careful methodological support.
