NASHVILLE, Tenn. -- A steady drizzle could not stop those who loved Lance Cpl. Richard Buerstetta from attending his funeral on Tuesday.

Buerstetta, 20, and Tyler Overstreet, 22, were killed last week when a roadside bomb exploded near their Humvee in Iraq.

One-by-one mourners made their way into St. Matthew Catholic Church on Tuesday. A collage in memory of Buerstetta rested in the entrance of the church.

"Lance Cpl. Richard Buerstetta was one of the finest men we've ever known," said Martin Hilber, who was to become Buerstetta’s father-in-law. "Richard was an integral part of our family. The pain is immeasurable.”

Buerstetta was laid to rest at the Middle Tennessee State Veterans Cemetery.

"You can tell he's missed amongst his family, friends and comrades. It's just sad," said Buerstetta’s former teacher Jerry Clark.

Overstreet To Be Laid To Rest On Thursday

Overstreet’s visitation is Tuesday and Wednesday at the Alexander Funeral Home in Gallatin, Tenn.

His funeral will be Thursday at the Hendersonville First Baptist Church.

Both men were members of the third battalion of the 24th Marine Regiment.
