Tony Stewart has been unable to escape the one-year anniversary of Kevin Ward Jr.'s death that took place on Sunday. But that may have played a role in his idea to help another family dealing with its own tragic deaths.

WHOTV.com reported that the 44-year-old Stewart donated $1,400 to the family of Jamie, Carson and Christian Singletary, who were killed last week in New Sharon, Iowa, when their car was hit by a truck at an intersection.

Jamie was 16, Carson 13 and Christian 10.

Stewart is in Iowa for the Knoxville Nationals, the biggest week for sprint car racing in the country, according to Fox Sports. Stewart had a chance encounter with Ralphi Munson, a friend of the Singletary family who was planning to sell four tote bags of racing memorabilia and donate the proceeds to the family.

Stewart overheard a conversation she was having about the bags with a friend, approached her and gave her $700 for the memorabilia, WHOTV.com reported.

Munson told the station that Stewart told her, "I overheard everything and I want to do this for the kids."

She added that she joked with him that the actual tote bags themselves cost extra. That's when Stewart phoned someone to bring him $700 more to make the total $1,400.

"One of the totes contained racing shirts for kids and Munson says Stewart told her to keep them and give them out at the raceway to any kid who looks like they need one," WHOTV reported.

Stewart finished last in a NASCAR race at Watkins Glen, N.Y., a venue he missed last season because of the tragic accident with Ward in which Stewart's car struck him and sent him airborne and to his death.

Ward's family last week filed a civil lawsuit against Stewart, claiming that he revved the engine as his car approached Ward, who had gotten out of his vehicle and was walking toward Stewart, forcing the car to swerve into Ward and killing him.

"A jury needs to see the video, learn of Tony Stewart's past, and give the verdict that delivers justice," Mark Lanier of The Lanier Law Firm in New York, which is representing the family," told the Orlando Sentinel. "Tony's actions took the life of a marvelous young, talented man."
