Two children were killed and their mother was seriously injured after they were attacked by their family dogs Wednesday afternoon, KTLA sister station WREG reports.

The Shelby County Sheriff’s Office said the attack happened inside a home in the 700 block of Sylvan Road near Shelby Forest State Park in the Memphis area around 3:30 p.m.

Deputies say two dogs attacked a 2-year-old girl, a 5-month-old boy and their mother.

Shelby County Sheriff Public Information Officer John Morris said both dogs appeared to be pit bulls and were taken by animal control.

Both children were pronounced dead at the scene. The mother was transported to Regional One Health in critical condition. She was later upgraded to stable condition.

Thursday afternoon, the Sheriff’s Office announced that the dogs responsible for the attack were euthanized by Memphis Animal Services.

This is still an ongoing investigation, and it remains to be seen if charges will be filed, WREG reports.
