DAYTON, Ohio -- Police in Dayton say a dog has attacked and killed a 7-month-old boy.
Police tell The Dayton Daily News that the baby's step-grandmother was watching the infant for the day when her dog attacked and killed him Sunday afternoon.
CBS affiliate WHIO reports that a neighbor called 911 in a desperate effort to get help.
"She just knocked on my door, bangin' on my door, She had a baby in her hand. The baby's not breathing. You need to get here now." the neighbor told the dispatcher.
A Montgomery County coroner's investigator says the baby, whose name hasn't been released, is from another state.
An autopsy is planned for Monday.
An animal control officer removed the dog.
Montgomery County records show an American Staffordshire terrier, which resembles a pit bull, is registered at the address where the baby was killed.
A June 3 police report shows the same dog attacked and injured another dog before it got away.
People who gathered at the home after the attack cried and screamed. Police say the step-grandmother was extremely distraught.
