"They changed hair color every month," Robert Roys said, smiling for a moment.
"It's going to be hard not having them around because they were there all the time. I love them with all my heart and they'll always be here, in my heart," said Sheryl.
Grief in Ohio
Hours earlier and nearly 1,400 miles away, in Warren, Ohio, six teenagers were killed when an SUV struck a guard rail and flipped into a pond.
They were among eight teens who had crammed into the Honda Passport, which was later reported stolen. It was built to seat no more than five.
None of the dead had been wearing a seat belt, authorities said.
The teenagers were speeding down a two-lane northeastern Ohio road, authorities say.
Alexis Cayson, 19, was behind the wheel, the highway patrol said.
Those who died alongside her were: Andrique Bennett, 14; Kirklan M. Behner, 15; Daylan Ray, 15; Brandon A. Murray, 14; and Ramone M. White, 15. All were from Warren.
The two survivors escaped by breaking the rear window in the submerged vehicle, Ohio State Highway Patrol Lt. Brian Holt said. They ran a quarter mile to a nearby home and called 911, he said.
Holt said weather was not a factor in the wreck -- the deadliest in his county's history and the worst in Ohio in at least three years.
Monday night, mourners held a vigil near the guard rail and alongside a makeshift memorial of Teddy bears and a cross.
They released helium-filled balloons into the air to commemorate the dead.
"It's numbing. It's confusing. It's hurtful," said Charlene Blackwell, whose nephew Ramone White was among the dead.
Grief counselors visited area schools Monday to help students and staff with the emotional aftermath.
