Investigators say beer cans were found inside the car, but they still can't say whether the boys were drunk or who was driving the car.
Monday was the first day back for students at Utica Community Schools since the crash. Their hearts are heavy, but ready to heal with a little help.
"It's a very, very strong community," said Tim McEvoy, Utica Community Schools "And while these are difficult times, this community has always rallied around its kids.
"We have grief counselors at all of our high schools that are working with students. So if students need assistance or if we identify students who need additional assistance, we have counselors available to them."
Two students who died in the accident Jonathan Manolios and Emanuel Malaj attended Stevenson High School. The third victim, Michael Wells, went to Henry Ford II High School.
Friends have already organized several vigils to remember them and to pray for Greg Bobchick, whose condition has improved and Joe Narra, who remains in critical condition.
"It's been rough, the community has taken big blows and tough tolls," said one student. "But we're going to get through this together."
The Macomb County Sheriffs Department confirms that there was alcohol found inside the teens' speeding Jaguar. It lost control and ended up in the Stony Creek River.
Only one person was wearing a seatbelt at the time. Everyone else was ejected.
"It is a sad moment," said one student. "Being friends with people you grew up with ... I don't know."
Instead of celebrating another year of school gone by, friends and family are now preparing to attend three funerals in the coming days.
A GoFundMe account has already raised nearly $20,000 for one of the victim's families. A sign of love and loss.
"We are a very strong community," McEvoy said. "There's been a tremendous outpouring of love and support for our students and for each other."
Grief counselors will remain at the school for as long as students need someone to talk to.
Toxicology results will likely take weeks to determine if alcohol played a factor in the crash.
