Lane had 30 grandchildren and eight great-grandchildren.

"He loved being a grandfather," said Gregoria Lane, the victim's wife.

She said Lane always brought her flowers.

Lane was on the way to pick up his wife from work when he was killed.

When he didn't show up, she got another ride home and passed by the accident scene.

"It's not fair that something like this happened to him by somebody so stupid," said Mena Norman, Lane's daughter.
