Family and friends of 17-year-old Boyd Shiro Maycry are grieving tonight.
They want to know how a night of partying at Sandy beach ended with the young man found dead on the highway.
A patrol officer came across the body and thought he may have been hit by a car
But an autopsy found that his injuries are not consistent with a car collision.
"We believe he may have been a passenger in a vehicle. We are asking for any information from witnesses, or from anyone who may have been driving in the area at the time," said Crimestoppers' Kim Buffet.
The medical examiner’s office said the young man died of craniocerebral injuries, or traumatic head injury.
The Hawaii National Guard says Maycry graduated from the Big Island’s Youth Challenge program in December 2011 and that he lived in Kalihi with his family.
Maycry's grandfather was struggling to deal with the sudden loss of the boy named after him.
As a pastor of a local Korean church, Shiro Timothy came to Hawaii 20 years ago. His daughter and his grandsons joined him 10 years later.
"He was just a nice boy, very humble. The sad thing is, the mother and father are not here now. They went back to Micronesia," said Timothy.
Maycry’s mother went for a vacation and isn’t due back until Monday.
His older brother, who was at Sandy's last night, recalled how he hadn’t seen Boyd for about half an hour.
"At that time we were about to leave and we realized he was missing " said Anthony Maycry.
That’s when the older Maycry had a bad feeling, and ran to the police who had stopped traffic along the highway.
He recognized his brother's shoes and shirt.
“I just couldn’t believe it. He is my little brother. He is little, but he is big, yeah?"
He is appealing for anyone who saw anything to come forward.
“I want to know what happened," Maycry said as his voice trailed off.
Anyone with information should call Crimestoppers.
