The body of Augustine, who threw his six-year-old daughter into the Adyar River on Monday before jumping in himself, surfaced on the river on Tuesday morning.
Local residents spotted the body around 7.30 a.m. and called the police.
On Monday morning, Augustine, a 42-year-old construction worker from Injambakkam flung his daughter Rosalin into the river and tried to throw in his son Dinesh too, but was stopped by his wife, Vimala Rani. He then jumped into the river.
Two youngsters who were nearby, jumped in and saved the girl, but they could not save Augustine.
Fire and rescue service personnel had searched for his body until Monday evening, but could not find it.
Adyar police inspector Rajiv Prince Aroon, said Augustine had been depressed. The family had been in the area to visit Vimala’s brother. “They were walking towards a prayer hall on Greenways Road when the incident took place,” he said.
