A 23-year-old engineering student in Thiruvananthapuram, was arrested on Thursday by the police for the murder of his 51-year-old mother.
The state police arrested Akshay Ashok, after keeping him in custody for two days, following his confession of the brutal act.
His mother, Deepa's charred body was found from the waste yard of their house on Tuesday morning.
Ashok himself had alerted the police on Tuesday stating that a charred body was found in their backyard. He also said that his mother was missing since Monday evening.
The police took him into custody after they found him changing his statements.
During the interrogation, Ashok confessed that he and his mother were not on talking terms and on Monday afternoon, he had pushed her down. He then strangulated her to death using a bed sheet, he told the police.
According to the police, after he ensured that his mother was dead, he burned her in the place where they normally burn the waste, using petrol.
Ashok has completed his engineering course earlier in 2017, and was waiting to clear a few of the remaining papers. His father was employed in Muscat, while his sister was married and in UAE.
Both of them have arrived in Thiruvananthapuram, after the murder.
The police were awaiting the DNA results of the dead body, as that would confirm Deepa's death.
The body was yet to be handed over to the family. Police are also probing Ashok for drug-use.
Earlier on Tuesday, after the body was found, Peroorkada Sub Inspector Sreekumar VM had told TNM, â€śThe spot from where the body was found makes us suspicious about the nature of the death. Have you ever heard of someone setting themselves ablaze by coming to a spot where people dispose waste? That is quite unusual as far as we know, and as per our experience. We havenâ€™t ever seen someone attempting suicide by choosing such a spot. The chance of that happening is very less. We are investigating all aspects.â€ť
