Idukki: A 23-year-old man, suspected to have killed a plus two student in Idukki, was found hanging from a tree on Tuesday, police said.
The body of Arun was found just a few meters away from the spot where Reshma's body was lying in a pool of blood in Pallivasal on Friday night.
Some locals noticed the body hanging from a tree and alerted the police.
Arun, a paternal relative of Reshma, had been missing since the day she was found murdered.
Investigators had begun to suspect him after Arun and Reshma were seen walking together in a CCTV footage retrieved from a local resort in Idukki on the same day. However, a police official said they could tell Arun had murdered Reshma only after establishing all evidence scientifically.
Circumstantial evidence was pointing towards him.
His mobile phone was recovered from near the girl's body," he said.
