LexisNexis.com -- A San Antonio Marine reservist was killed by a suicide bomb in western Iraq, his family learned Saturday night. Lance Cpl. Lance Tanner Graham, 26, was a gunner riding in the back of a Humvee when two suicide bombers closed in on his convoy, ''and that was that,'' said Suzanne Hildebrand, a close friend of Graham's family. The Associated Press reported seven U.S. service members in Iraq were killed in violence over the weekend.

It was unclear if Graham's death was part of that tally. Three of the U.S. victims were soldiers killed Sunday in bombings in central Iraq, the U.S. command said. On Saturday, three U.S. Marines and a sailor were killed fighting with insurgents in western Iraq, some of whom fought from inside a hospital, the military said. More than 300 people, including American forces, have been killed in a torrent of insurgent attacks since Iraq's Cabinet was sworn in April 28. Graham was assigned to the Weapons Company of 3rd Battalion, 25th Marines. Family members were not available for comment Sunday. Hildebrand said she had spoken with Graham's father, Joe Graham, who had served in Vietnam. Graham was proud of his son, a Madison High School graduate, she said, but his loss was almost unbearable. ''We talked about the fact that you tell your children what you did, and when they follow in your footsteps it sometimes makes you proud, and sometimes it scares you,'' she said. ''He was the light of our life. He was my son's best friend.''
