Prosecutors disclosed on Thursday that a family tracking app on a man’s phone led to his arrest after he allegedly scattered his young wife’s dismembered remains across New York City. The accused, Rupchand Simboo, 74, faced murder and concealment of a human corpse charges after being connected to a series of gruesome discoveries in Queens.

Simboo was arraigned late Wednesday as investigations revealed that sanitation workers had found a woman’s decomposed torso in September. The torso, wrapped in a blanket and abandoned near a wooded area off 149th Avenue and Brookville Boulevard, was later identified as Simboo’s 33-year-old wife, Salisha Ali.

Further searches last week uncovered Ali’s head, legs, and arm in the Jamaica Wildlife Refuge. The discovery followed a focused investigation into Simboo’s mobile phone, prosecutors shared.

Authorities had tracked Simboo’s movements using the Life360 app on his phone, revealing his presence at the wildlife refuge on July 14—the day after Ali was last seen alive. Additionally, GPS data showed he had been near the location where Ali’s torso was discovered, according to the prosecution.

Detectives had tracked Simboo’s GPS coordinates through the Life360 app on his phone and found he was in the reserve on July 14 – the day after his wife was last seen alive, according to prosecutors.

He had also been by Brookville Boulevard and 149th Avenue, where Ali’s torso was found, prosecutors said.
