The death earlier this week of Thomas "Tommy" Marth, the Killers' saxophonist who played on live tours and on their albums Sam's Town and Day & Age, has been officially ruled a suicide by the Clark County Coroner, Reuters reports.

Marth, who was 33, was found dead from a self-inflicted gunshot wound to the head, said officials in Clark County, Nev., where the band's hometown of Las Vegas is located.

The band took to Twitter to mourn the loss: "Last night we lost our friend Thomas Marth. Our prayers are with his family. There's a light missing in Las Vegas tonight. Travel well, Tommy."

The death comes as the Killers are preparing to return from a hiatus following the release of their last album, 2008's Day & Age. The band, fronted by singer Brandon Flowers, recently returned to the studio to work on their next album.
