Absence of explanation under Section 106 Evidence Act completes chain of circumstances in matrimonial homicidal death.

The deceased, Preeti, married the appellant Sudhakar in 2012.

On May 8, 2015, the first informant (PW-1/father) received a call from the deceased claiming her in-laws were beating her and intended to kill her.

Upon arrival, PW-1 found her dead in the matrimonial home.

The autopsy revealed "asphyxia due to strangulation" with a fractured hyoid bone and six additional contusions on the limbs and abdomen.

Although the FIR initially alleged dowry death, nine prosecution witnesses of fact, including the deceased’s father and brother, turned hostile during the trial, disowning their statements regarding dowry demands.

The Trial Court acquitted the accused of dowry-related charges but convicted the husband (Sudhakar) and parents-in-law (Gauri Shankar and Munni Devi) for murder under Section 302/34 IPC based on circumstantial evidence.

Section 302 read with Section 34 of the IPC regarding common intention in murder.

The Panchsheel principles of circumstantial evidence established in Sharad Birdhichand Sarda v. State of Maharashtra, requiring a complete chain of evidence excluding any hypothesis of innocence.

Section 106 of the Indian Evidence Act, 1872, as interpreted in Balvir Singh v. State of Uttarakhand and Trimukh Maroti Kirkan v. State of Maharashtra, which stipulates that when a crime occurs in the privacy of a house, the inmates must provide a cogent explanation for facts especially within their knowledge.

The Court determined that the medical evidence—specifically the horizontal nature of the ligature mark, the fractured hyoid bone, and the presence of multiple struggle-related contusions—squarely pointed to homicidal strangulation rather than hanging.

Despite the hostility of PW-1 to PW-9, the Court held that the FIR remained the earliest account of the crime and could not be entirely discarded.

Applying Section 106 of the Evidence Act, the Court reasoned that since the deceased died a violent death within the matrimonial home, the appellants (as sole inmates) were the only ones who could explain the occurrence.

The Court rejected the defense’s vague suggestion of "unknown intruders" because no other family member was injured and no report was lodged by the appellants themselves, making their silence or false explanations an additional link in the chain of guilt.

The High Court affirmed the conviction of Sudhakar, Gauri Shankar, and Munni Devi under Section 302/34 IPC and the sentence of life imprisonment; the appeals were dismissed and the parents-in-law were ordered to surrender immediately.
