On July 7, 2025, in Muzaffarpur, Bihar, India, Mohammad Mumtaz, a local panchayat employment servant (Rozgar Sevak), was stabbed to death inside his home on Ramraji Road. His educated wife, Saba Firdaus, initially claimed she woke up after a power cut to find her husband dead, then later changed her account to claim masked intruders had stabbed him in front of her. Police grew suspicious due to the glaring contradictions and the disappearance of the home's CCTV DVR. Upon sustained police interrogation, Saba confessed that she had planned the murder and stabbed Mumtaz 15 to 16 times while he slept. She initially blamed domestic abuse and her husband's alleged extra-marital affair. However, digital forensic analysis of her phone revealed that Saba herself was having a secret affair with a relative, which Mumtaz had discovered and monitored via CCTV cameras at their gate. Phone records also showed Saba had searched Google for ways to commit murder and destroy evidence, binged over 100 crime fiction episodes, and posted a threatening note on the wall reading, 'It is acceptable for me to lose, but I will play a big game.' The weapon was recovered, and post-mortem analysis confirmed 17 stab wounds, with police investigating potential toxicology and co-conspirator involvement.

Infidelity
The case reflects a pattern of marital conflict driven by mutual allegations of infidelity, intense domestic resentment, and extreme pre-meditated escalation. Although the suspect initially claimed to be the victim of ongoing domestic abuse due to her husband's suspected affair, police digital forensics established that she was engaged in an affair with a relative. When her husband attempted to restrict and monitor her movements through gate CCTV surveillance, the suspect consumed online crime media and executed a deliberate, fatal attack.
Police initially responded to screaming at the home on Ramraji Road on July 7, 2025. Saba Firdaus changed her statement twice before police confronted her with evidence, leading to her confession. Police recovered the murder weapon (a knife) based on her directions. Post-mortem examination revealed 17 knife stab wounds. Digital forensics recovered her Google search history on how to kill and destroy evidence, as well as evidence of her extra-marital affair. Police are awaiting toxicology reports to verify if Mumtaz was drugged or incapacitated prior to the stabbing and are investigating whether her relative was an accomplice or involved in removing the missing CCTV DVR.
The investigation experienced initial confusion due to Saba Firdaus presenting two contradictory stories: first claiming she slept through the incident during a power cut, and later claiming masked intruders stabbed her husband in front of her. Further confusion arose from the missing CCTV DVR and a handwritten wall note reading, 'It is acceptable for me to lose, but I will play a big game.' Interrogation and phone forensics resolved the contradictions.
Forensic evidence, digital search logs, and physical recovery established that Saba Firdaus planned the killing following escalating marital arguments over her affair with a relative. To prevent intervention, she attacked Mumtaz while he slept, inflicting 17 knife wounds. She posted a cryptic note on the study wall, removed the CCTV DVR to destroy entry footage, and feigned severe grief while telling contradictory stories to neighbors and police before breaking down during interrogation.
The case demonstrates a high-risk dynamic where domestic distrust and intrusive surveillance by one partner intersected with pre-planned lethal violence by the other. The suspect displayed calculated premeditation by conducting extensive research on online murder methods, acquiring crime techniques from media, removing digital evidence (the CCTV DVR), and inventing false narratives to misdirect law enforcement.
Online search history, media-inspired crime planning, sudden removal of recording hardware (DVR), and glaringly inconsistent statements immediately after a crime serve as major indicators of intimate partner premeditation and deception.
The absence of forced entry signs, lack of injury to the wife or three young children in a small home, and immediate contradictory accounts regarding the power cut and intruders were key early warning signals.
Key clues included the missing CCTV DVR, the handwritten note on the study room wall, the absence of defensive wounds on the victim, and Saba's evolving accounts during repeated questioning.
Strongest evidence includes Saba's confession, recovery of the murder weapon based on her statement, phone records showing Google searches on murder techniques and evidence destruction, chat history confirming her affair, and the post-mortem report recording 17 stab wounds.
Follow-up police analysis of Saba's mobile phone overturned her claim that Mumtaz was abusing her over his affair, revealing instead that Saba had an affair with a relative and Mumtaz was using gate CCTV cameras to monitor her.
Unresolved aspects include pending toxicology results to determine if Mumtaz was drugged before the attack, the location of the missing CCTV DVR, and whether Saba's relative participated in planning the murder or concealing evidence.
