Dilip was arrested based on Renu's testimony - Sushma's sister who lived with them. While Dilip admitted to shoving Sushma and threatening to kill her during a heated argument, he insisted he did not actually kill her and claims he cannot recall the exact sequence of events. The police had little other evidence but enough circumstantial testimony to charge him.

During his trial, Dilip was examined by Dr. Trivedi who recommended keeping him under hospital observation due to his erratic behavior. On a stormy night, Dilip managed to slip away from the hospital facility, escaping into the night while authorities were likely distracted by the severe weather.

The body belonged to Jagmohan, Rekha's husband. Dilip discovered it during a midnight search of the house when Rekha was nowhere to be found. Rekha initially dismissed it as Dilip's imagination, but the body was later confirmed to be Jagmohan's, found outside the house rather than in the bathroom.

Rekha confessed that she and Inspector Diwan were having an affair, and that her husband Jagmohan was murdered when he walked in on them together. Overcome by guilt and remorse over her role in the murder and the web of deception she had maintained, Rekha took her own life.

Renu, Sushma's own sister, was the actual killer. Inspector Karwe discovered this through forensic evidence - a fragment of Renu's bracelet found in Dilip's color palette and fingerprint analysis. Despite testifying against Dilip and seeing him arrested for the crime, Renu was the one who actually murdered Sushma.

Inspector Karwe uncovered two key pieces of evidence: a fragment of Renu's bracelet discovered in Dilip's art color palette and fingerprint analysis that matched Renu to the crime scene. This forensic evidence proved Renu was the actual killer and completely exonerated Dilip of Sushma's murder.

The specific motivation for Renu's crime is not explicitly detailed in the summary, but she testified against Dilip knowing he was innocent while being the actual killer herself. This allowed her to deflect suspicion away from herself and onto her brother-in-law, living in the same house and having direct access to the victim.

Yes. Rekha confessed that she was having an affair with Inspector Diwan, and her husband Jagmohan was murdered when he walked in on them together. This explains why Dilip suspected Diwan of helping cover up the crime - Diwan had visited Rekha's house before and taken a cigarette lighter, which Dilip used as evidence of their connection.

Inspector Karwe pursued a different investigative path than Diwan, conducting forensic analysis. He found a fragment of Renu's bracelet in Dilip's color palette - the same palette Dilip used for painting. Combined with fingerprint evidence, he was able to prove that Renu, not Dilip, was responsible for Sushma's death.

Dilip pointed to an unused cigarette lighter that Inspector Diwan had taken during a prior visit to Rekha's house. This was significant because Diwan publicly denied ever visiting Rekha's home or knowing her. The lighter served as proof that Diwan was lying and potentially colluding with Rekha to hide her husband's murder.

The conflict began when Sushma asked Dilip to accompany her out during one of his intense painting sessions. When he refused, she destroyed one of his canvases in anger. This act sent Dilip into a rage - he shoved her, threatened he would kill her, and stormed out. When he returned, Sushma was dead.

After Jagmohan's body was discovered, investigators found a piece of prison-issued cloth clutched in his hands. This piece of Dilip's prison uniform was used to link Dilip to Jagmohan's murder, making it appear he had killed Rekha's husband. However, this was part of the false evidence trail that framed Dilip.
