HARRIS COUNTY, Texas- Marc Gardiner doesn't want to try and process the unexpected-- the news about his younger brother Dalton.

"We didn't always get along but he was still my brother," Marc said. "He wasn't perfect but he did a lot."

He was also trying to do a good deed, and it went bad.

Dalton and three others were helping to raise a flooded home on Olana Drive in northeast Harris County Thursday when the house shifted and collapsed, killing Dalton and Shad Moore.

Marc said his brother was not working at the house in any official capacity. He said they were only working for gas and food.

Marc said his brother leaves behind a wife and a 7-year-old daughter.

"I literally saw him give the shirt off his back to somebody that needed it," Marc said.
