"No sleep & anxiety, please let this pass sooner", Devy Saldivar, 16, wrote on Facebook around 5:30 a.m. Sunday.
Saldivar's sister-in-law, Virginia, told The Associated Press Tuesday that the same deputies came to the suburban Houston home where she and her husband have stayed since volunteers evacuated them Monday for information about the children, aged 6 to 16, and her in-laws.
As of Monday, the Saldivars are among at least 14 dead, though that number will nearly undoubtely go up as the water recedes and the true impact of the storm becomes known.
"As the water came up on them in the van, I know they were holding hands".
By the time Harvey bore down on Houston, it was a Saldivar neighborhood, through and through. "The neighbors woke him up", Ric said.
"What keeps going through my mind is the struggle, how they were trying to get out of the vehicle to save themselves", said Parades.
Ric Saldivar said the Harris County Sheriff's Office told him his brother was stuck in the water for 45 minutes when they found him.
The driver - the children's great-uncle - was able to escape, but the van sank too quickly for the victims to be rescued, KHOU 11 reported.
"They haven't located the bodies, but from what my aunt has said, the auto is still in the water".
Manuel Saldivar, 84, and his wife Belia, 81, were in the vehicle with their great-grandchildren - Devy Saldivar, 16, Dominic Saldivar, 15, Xavier Saldivar, 8, and Daisy Saldivar, 6 - when the rushing waters pushed the van off the road, family members told NBC News.
They were traveling to his home on Sunday when their van was swept away.
The dentist who employs the children's family member, Esmeralda, who is a dental assistant, started a GoFundMe page to help benefit the grieving family. "He loved his family and he would defend them against anything". Relatives said they could not really begin to grieve until it was found and their worst fears were confirmed.
Danny and his wife weren't home; they had vacated the neighborhood hours earlier, Ric said.
Ms. Salazar, who works at Legal Aid of Western Ohio and Advocates for Basic Legal Equality, said her co-workers provided strong support.
"He was yelling at the kids to climb out of the back of the van; I'm sure they couldn't reach it", Ric told the outlet.
