OXFORD, Fla.—A pet Burmese python measuring more than 8 feet long broke out of a terrarium and strangled a 2-year-old girl in her bedroom Wednesday at a central Florida home, authorities said.

Shaiunna Hare was already dead when paramedics arrived at about 10 a.m., Lt. Bobby Caruthers of the Sumter County Sheriff’s Office said.

Charles Jason Darnell, the snake’s owner and the boyfriend of Shaiunna’s mother, discovered the snake missing from its terrarium and went to the girl’s room, where he found it on the girl and bite marks on her head, Caruthers said. Darnell, 32, stabbed the snake until he was able to pry the child away.

“The baby’s dead!” a sobbing caller from the house screamed to a 911 dispatcher in a recording. “Our stupid snake got out in the middle of the night and strangled the baby.”

Authorities did not identify the caller and removed the person’s name from the recording.

“She got out of the cage last night and got into the baby’s crib and strangled her to death,” the caller said.

The snake will be placed with someone who has a permit, pending an investigation into the girl’s death.
