Update: This story has been updated with additional suspect information.
WYOMING, Mich. -- Michael White was your typical 16-year-old boy who loved to skateboard, play video games and hang out with friends, family says.
It's been more than 24 hours since White's body was found by someone walking their dog just after 11 a.m. Saturday in Wyoming's Lions Park.
He had been out the night before to be with friends -- nothing usual for someone his age, members of White's family said Sunday afternoon. White's mother began worrying the next morning, when detectives made the call to family that he had been discovered.
"He was a very free spirit -- in touch with nature, loved fishing and hunting," said his aunt, Heather Stark.
They describe him as a sweet boy, an ordinary teen who just always saw the good in people. Perhaps he was naïve as well, said Stark, noting Wyoming police has someone in custody who knew White.
That person's name has not been released, aside from being identified as a 15-year-old Kentwood boy. Police believe others might be involved.
"He's not the type of person to see the bad in people, and he trusted the wrong person and ended up somewhere he shouldn't have been that night," Stark said.
An early investigation revealed White suffered some sort of blunt force trauma to his head, said Wyoming police Lt. Mark Easterly. Says Stark to the suspect: "Maybe he could have called 911 or something ..."
Michaela Tran's best memory of her brother is her last time with him, she said.
"I was having a hard day, and he walked across the big long hallway and gave me a hug," Tran said. "We just held each other for a long time, and (I) got to tell him I loved him.
"... At least I have a good memory since you never know when you're last going to see someone ... at least it wasn't a bad memory."
An autopsy is scheduled for Monday morning. A news media update slated for Monday afternoon has been postponed.
Anyone with information still is asked to contact the Wyoming Department of Public Safety at 616-530-7300 or Silent Observer at 616-774-2345.
