Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

KERRVILLE, Texas — Shock has turned into grief across Texas where at least 120 people died from flash floods and more were missing as the search for victims moved methodically along endless miles of rivers and rubble Thursday.

Sisters Blair Harber, 13, and Brooke Harber, 11, were killed, along with their grandparents, when surging floodwaters ripped through the community. Their parents were staying in a different home at Casa Bonita and survived, according to the family's GoFundMe.

Flash floods surged through in the middle of the night, but many local officials appeared unaware of the unfolding catastrophe, initially leaving people near the river on their own.
