NEW GLOUCESTER – Fellow high school students on Wednesday mourned 16-year-old Joshua Libby of Gray who was killed a day earlier in a vehicle crash on Route 100.

Meghan Landry, a 16-year-old classmate of Libby, stood in the drizzle Thursday night along Route 100. There, near the corner of Short Bennett Road, a memorial had been placed for the teenager.

“He loved to fish. He loved riding his bike; he was just always happy,” Landry said. “He was really outgoing and he knew everybody.”

Libby was not the kind of kid to stew in anger, said Landry’s mother, Laurie Goodenow. “He would just make a joke.”

By Wednesday afternoon, a memorial page had been set up for Libby on Facebook.

“Oh Josh, one of my very best students, always smiling and having fun! My heart is so sad,” schoolteacher Bridget Rogan Tidd wrote on the page. “This world has lost an amazing young man.”

Libby, a student at Gray-New Gloucester High School, was a passenger in an SUV that collided with a van at the intersection of Bennett Road in the afternoon, police said. A second passenger, 20-year-old Travis Dunn, also of Gray, was injured in the crash and taken to Central Maine Medical Center in Lewiston. The driver of the SUV, 18-year-old Benjamin Farynaz of Gray, also was taken to CMMC, along with the driver of the the van, Melvin Durland, 61, of New Portland.

Durland was listed in serious condition on Thursday, a hospital spokeswoman said. Dunn and Farynaz were upgraded from serious to fair, she said.

Police said the Ford Explorer SUV was eastbound on Bennett Road. It failed to stop at the intersection and was struck by the van, which was traveling on Route 100. The occupants of the SUV were trapped inside, police said. Troopers found alcohol in the SUV and are investigating whether alcohol was a factor in the crash, police said in a statement.

A Cumberland County Sheriff’s Department deputy is reconstructing the accident, Maine State Police Lt. Walter Grzyb said. Both drivers’ blood-alcohol levels are being tested, as required following any fatal accident, but no results were available Wednesday, Grzyb said.

A portion of Route 100 was closed for about four hours Tuesday due to the accident, Grzyb said.

Parents of high school students were alerted to the news of the accident by school officials Tuesday night.

About 100 Gray-New Gloucester High School students gathered at the school Tuesday night after Principal Paul Penna opened the school’s doors so students could gather and meet with guidance counselors after learning of Libby’s death, SAD 15 Superintendent Victoria Burns said. The school was kept open for at least two hours.

On Wednesday, counselors from the Center for Grieving Children were available for students following a school assembly, Burns said. Students also scribbled messages to Libby on a paper banner hanging from a hallway wall at the school, she said.

Maine State Police Sgt. Mike Edes told WGME TV Channel 13 on Tuesday that traffic enforcement was lacking in the area. Grzyb said Wednesday that Edes was not speaking for Maine State Police.
