A 7-month-old boy has died after his mother set them both ablaze following a fight with his father.

The horrifying episode unfolded last week at a home in Hayathnagar, a busy residential locality in the Ranga Reddy district of the Indian state of Telangana, where the couple, Venkatesh and Suvarna, lived with their infant son, R.Kannaiah.

According to reports, the couple had frequent fights since their marriage, and Venkatesh, who is reportedly an alcoholic, would harass his wife on a daily basis whenever he was in an inebriated state.

Police sources said, after one such fight on Jan. 11, Suvarna, doused their son and herself with liquid sanitizer and set them both ablaze. Neighbors, who were alerted by the woman’s screams, rushed to the home and managed to put out the fire.

Both mother and child were immediately shifted to a nearby private hospital and then to the Osmania General Hospital, where the infant died during treatment. Suvarna suffered serious burn injuries and is being treated at the hospital.

The Hayathnagar police had initially charged the mother with a case of attempt to murder, but following the death of her infant, the charges have been altered to that of murder.

The police are yet to make an arrest, according to reports.

In another case of murder-suicide, a young Florida mother shot her two sons to death before turning the gun on herself, according to the Pasco County Sheriff's Office.

The incident came to light when the woman’s husband walked into their Land O’ Lakes home Wednesday evening, Jan. 11, and found his wife and two sons lying dead in a pool of their own blood in the bedroom.

The boys were 9-months-old and 3, Sheriff Chris Nocco said during a press conference Thursday morning.

Sgt. Michael Rosa, who joined Sheriff Nocco during the press conference and is part of the Major Crimes Unit, said that a dispute between the couple may have led to the murder-suicide.

"People in relationships have arguments. Some people take it a little harder than others," Sheriff Nocco added. "And instead of reaching out to get help, people make horrific decisions, and it looks like last night somebody made a decision that is beyond horrific."
