Authorities say a 4-year-old Florida boy has died after being mauled by two pit bulls.
Hillsborough County Sheriff's Office spokeswoman Debbie Carter said Logan Shepard was visiting relatives Saturday night in Riverview. An uncle put the dogs in crates before the boy arrived.
Carter said Logan was left alone while his mother and other adult relatives were talking in another room. The adults heard screaming and discovered that the boy was not in the house.
Two deputies conducting a traffic stop nearby also heard the screams and rushed to the home. Carter said Logan was found in the front yard with the dogs standing over him.
Carter said Logan was pronounced dead at the scene.
No charges have been filed but the dogs were taken by the county's Animal Services.
