Michael McCown sent his 8-year-old daughter Linnie to a summer camp in central Texas trusting she would be safe.

Families of the victims killed at Camp Mystic during the Texas flood disaster spoke out at a hearing for a bill to improve safety at youth camps.

The parents of girls who lost their lives at Camp Mystic on July 4 will testify before the Texas Senate Disaster Preparedness and Flooding Select Committee in support of Senate Bill 1.

Camp Mystic and Richard “Dick” Eastland’s family expressed their support Thursday for Senate Bill 1 and House Bill 1, legislation aimed at improving safety at camps and communities along the Guadalupe River.

"I promised her she would be safe and OK. I told her camp was the safest place she could be and camp was a place she could make new friends and learn new things," said her mother, Carrie Hanna. "She not only wasn't safe. She died." Hanna said she received very poor communication about what had happened to her daughter.

They testified before Texas lawmakers for the first time since July 4, when storms engorged the Guadalupe River, killing their children.

The parents of Camp Mystic flood victims are scheduled to testify at a Texas Senate committee hearing on Wednesday.

Parents of "Heaven's 27" meet with Texas leaders, call for investigation and legislative action to prevent future tragedies.

The families shared stories of unimaginable grief and heartache as they pleaded with committee members to pass SB 1 to ensure Texas youth camps are safer.
