FORT WORTH, Texas -- The mother of a 9-month-old boy found dead in a car seat inside his caretaker's closet is speaking out.

Authorities in Tarrant County, Texas, said the caretaker placed John Norris in a walk-in closet Monday to let him sleep.

When the caretaker later checked on the boy, he was dead.

An autopsy revealed the child accidentally suffocated.

A police statement issued Tuesday said the child was improperly secured in a child car carrier seat and strangled on a bottom belt strap while sleeping. The boy's neck was caught between a chest buckle and a strap mechanism.

"He just started crawling on Sunday, and he was 9 months old yesterday," said Megan Norris. "I couldn't have been more blessed with another child. He changed my life. He really did."

At least 10 other children were in the home when the baby died.
