Questions still remain as to what killed a young mother who was found dead in the passenger seat of her car along a Philadelphia street nearly two weeks after she went missing.
An autopsy was performed on 22-year-old Nadia Malik on Friday, but the Philadelphia Medical Examiner said her cause of death is still pending as they await further testing. Officials say there were no obvious signs of trauma and are waiting for the results of additional tests, including toxicology, that could take another six to eight weeks to obtain.
The Delaware County woman's body was found inside her black Nissan along S. 30th Street on Thursday. She was reported missing by her family 12 days before, on Feb. 9.
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 Malik's ex-boyfriend Bhupinder Singh.
The 25-year-old was the last one to see the woman alive. He was found in Ohio, which is where his parents live, after authorities pinged Malik's cell phone, police said. Singh had the phone on him when he was found, according to authorities.
Singh, who has not been identified as a suspect in case, was arrested for violating his probation by leaving Pennsylvania. At the time of his arrest, the man 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 could be.
The man also allegedly showed detectives two Greyhound bus tickets -- one to New York City and another to Washington, D.C. -- showing he traveled to those cities during the time Malik was missing.
Authorities are working to bring the ex-boyfriend back to the area. He will arrive at Delaware County Prison on Feb. 27, according to officials.
Malik and Singh had three children together, one of which died as a baby under suspicious circumstances, according to Delaware County authorities.
Delaware County detectives plan to re-examine the baby's death, officials say, over concerns about the child's care. The other two children are in the custody of Malik's family.
