BUFFALO, NY — A toddler suffocated and died on a couch after a woman fell asleep on top of him at the end of a night of drinking, prosecutors in New York state said on Wednesday.

The woman, who is 5 feet 3 inches tall, weighed more than 200 pounds.

They said they would decide by Friday whether to charge the woman, who is 5 feet 3 inches (160 cm) tall and weighs more than 200 pounds (90.7 kg), with a crime. Her name was not released.

Chance Goforth, aged 18 months, died last week while his mother, Linda Parsons, 21, was entertaining friends.

"All the people were drinking but to what extent they were, that will be determined," Erie County District Attorney Frank Clark said.

"Our focus is on the woman who went to sleep on the child. It's tragic and whether it's criminal we will have to see."

Clark said the woman and the boy's mother, who has two other small children, told police they had started drinking Thursday afternoon and carried on into Friday morning.

Apparently, everyone either left the apartment or found somewhere to sleep by 3:30 a.m. Friday. Chance was found under the woman at 8 a.m.
