The ex-boyfriend of a missing Delaware County woman who was found dead in her car outside of Philadelphia's 30th Street Station return to Pennsylvania Thursday.
Nadia Malik, 22, of Broomall, Pa. went missing Feb. 9. Her sister, Mona Malik, told NBC10 she spoke to her the day of her disappearance.
According to Mona, Nadia was with her ex-boyfriend, Bhupinder Singh, while she was on the phone. Mona also says she heard her sister saying, “let me go," before she was cut off.
Singh, 25, was arrested on Feb. 12 in Cuyahoga County, Ohio on a probation violation. Investigators say Singh violated his parole by failing to report to his probation officer in Pennsylvania, changing his residence without permission and traveling outside the state without permission.
He remained behind bars in Ohio for more than two weeks. At the time of his arrest, Singh had a black eye and scratches on his face, police said. He allegedly told investigators Malik inflicted those wounds on him, but said he had no idea where she was.
Marple Township Police Chief Tom Murray told NBC10.com that he expected Singh to be returned to the area late Thursday. Late Thursday, county prison officials confirmed that Singh was back in the area.
Marple Township Police planned to question Singh Friday.
Singh, who had an on- and off-relationship with Malik, hasn't been charged in her disappearance. Malik and Singh had three children together, one of which died as a baby under suspicious circumstances, according to Delaware County authorities.
Investigators said that they found Singh by using Malik’s cell phone.
When questioned earlier about Malik’s disappearance, Singh told investigators that he last saw Malik in a parking lot with her car, according to police.
Parking enforcement officers had posted several parking tickets on the car and it was even towed from another location at one point because of a snow emergency. Questioned on why Malik's body went unnoticed for so long, police say the car has tinted windows and was covered in snow.
Sources tell NBC10 several pill bottles were found inside the car, some of which contained antibiotics prescribed to Singh.
An autopsy was performed on Malik on Friday, but the Philadelphia Medical Examiner said her cause of death was pending further testing. Officials say there were no obvious signs of trauma -- they are waiting for the results of additional tests, including toxicology, that could take another six to eight weeks to obtain.
