Trish Dillon of Katy, Texas comforts her son, Matthew Manuel, 19, while they sit in front of her son and his brother's gravesite at the Houston National Cemetery on Monday, May 27, 2019. Brett Manuel was an Army Ranger and died at the age of 22, when Matthew was 12, in an accident on base before his third tour of duty. "He was so happy with his life, and as a mom, that's what you want for your kids," said Dillon. Manuel was also an organ donor and the family has received letters and have even met some of the recipients of his organs. "It's like he still lives, helping others and that gives me some peace," said Dillon.
