UPDATE: Woman killed by suspected DUI driver was pregnant

"I can't explain it, I don't even know how to help my son," said husband Anthony Cruz.

Cruz and Leiwalo have a 9-year-old son together. The couple was anxiously awaiting the arrival of their second son in May.

Cruz says his wife was killed just blocks from her job. His unborn son died on scene as well.

"He was five pounds already. They were expecting him to be a nine-pound baby," said Cruz.

Although his life is shattered, Cruz says he is determined to keep going for his son. He says his goal is to make sure his child goes to college. That is what his wife would have wanted.
