Coast Guard Petty Officer Scott Ruskan rescued nearly 200 people during his first mission over the weekend from floods that killed over 100 people.

Rescuers searched the Guadalupe River for survivors of the Texas floods that killed more than 100 people over the July Fourth holiday weekend, with an unknown number of people still missing. The basin area was crowded with families and campers preparing to enjoy the holiday when pounding rain brought about catastrophic flash floods just before dawn Friday.

The National Weather Service began sending flash flood warnings that should have triggered cellphone alerts a little after 1 a.m., while local officials began posting on Facebook about four hours later.

CBS News analysis shows there were 22 warnings sent by the National Weather Service for Kerr County and the Kerrville area, but many residents say they didn't get alerts.

The downpours that swept away a children's summer camp and wreaked deadly havoc on huge areas of Texas caught holidaymakers by surprise. As the death toll passes 90 people, questions are being raised about whether adequate flood warnings were provided and why people weren't evacuated ahead of the deluge.

Gracie Hunt, the daughter of Kansas City Chiefs owners Clark and Tavia Hunt, mourned the loss of a 9-year-old relative killed in the Texas floods.

Janie Hunt, the 9-year-old cousin of Chiefs owner Clark Hunt, died in the fatal floods in Texas last week. According to the Dallas Morning News, Janie Hunt of Dallas was one of the missing campers from Camp Mystic in the Texas Hill Country.

Kansas City Chiefs owner Clark Hunt and his family are grieving the loss of a young family member who died in the Texas floods. Janie Hunt, 9, was at Camp Mystic in Hunt, Texas, when tragedy struck over the weekend.
