A court filing alleges that a man accused of killing three women was tracked via his cellphone to locations near where at least two of the women's bodies were found.
The assertions were contained in an affidavit filed in January by an Essex County prosecutor's office detective, seeking a court order to force Khalil Wheeler-Weaver to provide a DNA sample.
The 20-year-old Orange resident was indicted last month for the three murders and the attempted murder, kidnapping and sexual assault of a fourth woman last fall.
Through his attorney, he pleaded not guilty in a brief court appearance on Monday. He's being held on $5 million bail.
