NEW DELHI: Three members of a family – a couple and their elder son – were found murdered at their home in south Delhi’s Satbari Khark village on Wednesday. Their throats were slit with several knives and their heads smashed with bricks, said police.The victims were identified as Prem Singh (45), his wife Rajani (40) and their son Ritik (24). The younger son, Siddharth (22), is the prime suspect and is currently missing.Police said a PCR call was received at Maidan Garhi police station reporting that “there was blood all over the house” in Satbari Khark Gaon. The call was made by a passerby who noticed that the gate was open, saw blood inside the premises, and thought a youth had cut his hand with a knife. “On reaching the spot, cops discovered two bodies lying in a pool of blood on the ground floor and another on the first floor,” a senior police officer said.

Accused undergoingpsychiatric treatment Forensic Science Laboratory (FSL) experts and the district crime team were called in to examine the scene. The area was secured, evidence collected and the bodies photographed before being sent for post-mortem.Cops said evidence strongly suggested Siddharth’s involvement. According to cops, after the crime, he allegedly confided to someone he had “killed his family” and “would not live here anymore”.Locals also told police Siddharth had been undergoing psychiatric treatment for some time. During a search of the house, cops recovered treatment documents and medications allegedly belonging to him.“Siddharth was receiving treatment from several mental health institutions over the past 12 years, the documents revealed. He suffered from obsessive-compulsive disorder and showed aggressive behaviour. From local inquiry, it was also revealed that he was not very fond of his family due to psychiatric issues,” the officer said.While Prem Singh was employed in a private job, Rajani was a homemaker. Investigators said they are piecing together the sequence of events leading to the triple murder and the exact cause of death will be established after the post-mortem report. Further investigation is underway.
