First, Collins-Robinson's father told reporters that his son went to his apartment unit across the hall to use the bathroom, then later told police that his son fell asleep while giving the children a bath.
"It was an accident," he said. "That's all it was. It was an accident."
Collins-Robinson was allegedly living with the Youngs after he was displaced by a fire.
Defense Attorney Lance Sobelman said his client had an agreement where he would get the boys ready for school in the morning and pick them up while their father was at work.
"He referred the children as nephews and to Mr. Young as an uncle and he's been very close to them in the past year. And obviously he's distraught. He's emotional; he was crying at his arraignment, Sobelman said.
Officials say the temperature of faucet water should be no more than 112 degrees. The tub water that burned the children was 131 degrees, according to investigators.As of Sunday, Landon was showing a lot of improvement, and was up and playing with toys, his father said. Landon also has cystic fibrosis, though that has not affected his pain level, Joe said.
Young said he forgives Collins-Robinson and doesn't blame him at all.
"It's a tragic mistake. It really is a tragic mistake. And me getting mad and upset is just gonna take my focus away from my boys," Young said.
Collins-Robinson was held on $3,000 bail and ordered to stay away from the Young boys.
He has another open case for charges of operating under the influence, drug possession and receiving stolen property.
