Police said Ayushi allegedly tried to avoid suspicion after the incident by calling relatives and informing them, and kept crying, that her mother had died in an accident.
The investigation took a different turn after Neeraj's brother, Rakesh Kumar Sharma, approached police and shared concerns about earlier disputes within the family.
He reportedly told investigators that Neeraj had previously complained about harassment over property matters and had received threats from family members.
