Hundreds in Arkansas gather to honor slain U.S. Marine Staff Sgt. David Wyatt

Rebecca Wyatt holds a candle during a vigil for her father Marine David Wyatt August 7, 2015 in Russellville, Ark., at Russellville High School. Wyatt was one four military personnel killed in Chattanooga in late July. Family, friends and community members joined at the High School Stadium to honor Wyatt's memory with songs, memories and prayer.

RUSSELLVILLE, Ark. -- The hot air hung heavy - and so, too, did the mood -- inside the Russellville High School stadium Friday night as family, friends and community members gathered to remember Staff Sgt. David Wyatt, a U.S. Marine killed in the July 16 attacks at military facilities in Tennessee.

As dusk approached about 8 p.m., hundreds took their seats in the stadium's bleachers and listened to testimonies from a few of Wyatt's high school classmates, his Boy Scout Master, junior high track coach and eighth-grade history teacher.

At the end of the ceremony, the stadium's lights went dark, and flames from hundreds of candles illuminated the faces of those holding them. A small choir, accompanied by the strumming of an acoustic guitar, softly sang Amazing Grace.
