The 27-year-old had been hospitalized prior to being released and charged in the Bethlehem Township crash.
Police in Pennsylvania's Northampton County have spoken with the New Jersey man believed to have been driving the car involved in a May crash that killed all three passengers in the vehicle.
Terrell Barclay, 27, of Orange, and his legal counsel are arranging for his surrender to Bethlehem Township police, said Cpl. Shaun Powell with the department.
Bethlehem Township police Investigator Tony Stevens has been in touch with Barclay via telephone, Powell said.
"Right now he's in New Jersey, as far as we know," Powell said Saturday afternoon. "So far all the arrangements are still in the process basically."
Barclay could turn himself in to police as early as next week, according to police.
Cops looking for alleged driver in crash that killed 3
Barclay was the lone survivor when he allegedly crashed a rented 2015 Chrysler 200 into three parked vehicles at 1:22 a.m. May 6 in the 1800 block of Willow Park Road in the township. He emerged from the sedan on fire, and was so severely injured that he remained in a medically induced coma for months at Lehigh Valley Hospital, Salisbury Township.
Killer in the crash were Amanda Martin, 26, of New Ringgold, Schuylkill County; Ashlee Mosher, 29, of Easton; and Joshua Edwards, 28, of Easton.
Barclay left the hospital prior to charges being filed Friday. He faces 16 charges, including three counts of homicide by vehicle while driving under the influence.
Blood testing put Barclay's blood-alcohol content 90 minutes after the crash at 0.19, according to court records. Penalties begin for most drivers at a BAC of 0.08. He allegedly also had THC, the intoxicant in marijuana, in his system. Responders trying to help him remove his burnt clothing found on him a bag of marijuana, police said.
Stevens in court records sad Barclay at the scene was "being extremely uncooperative and kept attempting to get up and leave the area."
Barclay was driving while his New Jersey and Pennsylvania licenses were both suspended, police said. A .40-caliber Taurus Millennium handgun found in the road where Barclay had exited the burning car was found to have been stolen from Plainfield Township, according to police; Barclay had bought it for $100 in Room 273 of the Scottish Inn in Hanover Township, Lehigh County.
