The family of the Polk County marine killed in a training exercise last month, laid him to rest Saturday.

David Fenn was one of seven men killed when a mortar round exploded.

Seeing the American flag covered casket of 20-year-old Lance Corporal David Fenn being loaded into a hearst, was hard for everyone watching.

“I don’t feel like he’s gone. He can’t be gone,” said Fenn’s sister Melanie Fenn.

His childhood friend Brittany Roberts says she’s just happy to see the support. “This is really amazing how many people have come out to support David, his family,” Roberts said.

Even complete strangers came to give their condolences.

“It touches home this is home. And this is our sadness with their families,” said Marine Family of Central Florida member, Tera Williams.

“The thought that it could have been my child and then if it was, I can’t imagine. Which is why we’re here,” said military parents, Gina and Bobby McKillop.

The McKillops came close to experiencing the pain Fenn’s family is going through.

Their son was the first on scene when a mortar round exploded during a training exercise last month, killing Fenn and six others.

It’s tragedies like this that sadly brings together former military biker groups like the Lethernecks. They lead the precession for Fenn’s funeral Saturday.

“He’s one of ours. He’s a brother to us. Even though he’s deceased, he’s still part of us,” said Lethernecks of Florida President, Danny Johnson.

That feeling of brotherhood and family is something those who knew Fenn says he would’ve wanted.

People close to David Fenn tell me they’re devastated they have to say their goodbyes here at his final resting place but they take comfort in knowing he gave his life doing what he loved.
