Ozbilgen, an ex-boyfriend named a person of interest in her disappearance in November, likely killed Parze early in the morning on Oct. 31, according to Gramiccioni.
Ozbilgen admitted to killing her in a note he wrote to his parents before he took his own life in November, NJ.com reports.
In the note, he wrote “He had had enough and he could not do life in prison," Gramiccioni said. “Ozbilgen acknowledged he had dug himself a deep hole. He never disclosed where he disposed of Stephanie's remains."
Gramiccioni said the investigation remains ongoing, but prosecutors are confident Ozbilgen acted alone.
An autopsy is scheduled for Monday morning, according to Middlesex County authorities.
The body was found about a half-mile away from the area of a recent search for missing woman Stephanie Parze, who disappeared between October 30-31, 2019. About 150 people took part in the Nov. 29 search organized by Stephanie's father Edward Parze, according to the Asbury Park Press.
Parze was last seen about 10 p.m. on October 30, 2019.
