Subhash Chander faces three counts of first-degree murder, one count of homicide of an unborn child and one count of aggravated arson, and was denied bail by Judge Martin E McDonough.

Monika Rani (22), Rajesh Kumar (36), and their son, Vansh (3), were killed in the blaze. Rani was about five months pregnant, authorities said. Chander told police that he was upset with his daughter and son-in-law because they married without his consent and he considered Kumar to be from a “lower caste”, said First Assistant State’s Attorney Robert Milan. Chander went to a gas station to buy gas for his son, but decided to give it to his daughter instead.

After arriving at her door, he said, Kumar told him that it was late and asked him to leave. He told police that Kumar started to push him and some of the gas from the container in his hand spilled onto the carpet just inside the door. Chander told police that he became “upset and angry” and pulled a lighter from his pocket and set the carpet on fire. Chander said that he did not call police or the fire department to report the fire, nor did he call his daughter to make sure she and her family were safe.

The victims died of carbon-monoxide poisoning and smoke and soot inhalation, and their deaths were ruled homicides on Monday by the Cook County medical examiner’s office. When fire personnel arrived, residents were jumping from the balconies.
