EDISON — The Edison teenager who crashed his parents' car into another vehicle on Route 27 on Tuesday night, killing him and two other people, was attempting to kill himself and had written a suicide note, law enforcement sources told The Star-Ledger today.

The teenager, a 15-year-old student at John P. Stevens High School in Edison, had written a suicide note on his body, according to the sources, who asked not to be identified because they were not authorized to discuss the case.

A law enforcement source and several classmates who requested anonymity identified the driver as Srijan Saha of Edison. Saha was interested in cars, rap music and art, according to classmates and his personal Facebook page, which says the teen was raised in Detroit, Mich.

Edison Police Chief Thomas Bryan declined to comment. In a statement released late Wednesday night, Acting Middlesex County Prosecutor Andrew Carey said the crash was being investigated as a "suicide-homicide," but did not identify the teenage driver.

Mohammed Zia, 46, and his brother-in-law Ali Behzad, 36, both of Edison, had gone out for a late night cup of coffee and were driving north on Route 27 near the Stony Road intersection when the teen's car struck theirs head-on around 12:30 a.m., authorities said. In his statement, Carey said the teen's vehicle veered into oncoming traffic shortly before the crash.

The teenager and Behzad were pronounced dead at the scene, according to Carey. Zia died at Robert Wood Johnson University Hospital a short time later.

On Tuesday, Bryan said it was unclear why the teen was driving, but confirmed the 15-year-old had borrowed the vehicle without his parent's permission.

The wreck was one of two fatal crashes in Edison on Monday and Tuesday that left four people dead. On Monday afternoon, Sister Nora Ashe, a 65-year-old nun and high school teacher from Brooklyn, was killed in a two-car crash on Woodbridge Avenue.

Her sister and sister-in-law were seriously hurt and remain in critical condition at Robert Wood Johnson University Hospital in New Brunswick, Bryan said.

Earlier today, several classrooms at J.P. Stevens High School held a moment of silence for the 15-year-old. Students said the fatal crash was talked about all day on school grounds.

"The district's prayers are with the late student's family, friends, students, staff, and community, during this very difficult time of extreme sorrow and grief," Superintendent Richard O'Malley said in a statement. "The police investigation is active and continuing and at this time we ask everyone to continue to keep those killed in this tragic incident and their families in their thoughts and prayers."

An e-mail to O'Malley was not immediately answered.
