KNOXVILLE, Tenn. (WATE)- The father of an 11-month-old child who died after being found unresponsive in a Knox County bathtub Wednesday is not blaming the child’s mother.

Brandon said he isn’t blaming Leonardo and calls Aiden’s death “an accident.”

“She’s just awesome as a mother. I don’t want to see her in prison, she does not deserve to be there. she’s a really loving and caring person. she really is,” said Brandon.

Brandon and Leonardo were not together at the time and do not live together, he was not present Wednesday night.

“It was just the wrong timing, bad timing, unpredictable, really. No one can see into the future, so how can you even know that was even going to happen?” said Brandon.

According to an arrest warrant, Leonardo told police she put the 11-month-old Aiden Xavier Leonardo and her 23-month-old in the bathtub with 4-6 inches of water before going outside to smoke a cigarette and have some, “me time” around 8 p.m. Wednesday. She said she was outside for about 10 minutes.

Leonardo said when she returned, her daughter had turned the water back on, filling the tub to the top. She said Aiden was floating on his back while her daughter stood in the tub.
