Emma rode her bike near her home in southwest Detroit on Monday as the dogs fled the neighbor's yard and attacked her, the station reported.

"You have not done anything," said Stapleton.
Witnesses tried to rescue the girl and the police said someone shot one of the dogs. Emma was taken to the hospital but died of her injuries.
"This is their neighborhood, they should be able to be free and do what every child does – walk around, ride a bike – they should not" I'm scared to be in their own neighborhood too "said Stapleton to WDIV." This is just very devastating. Very, very hurtful for this family. "
The owner of the three dogs was arrested, but the police did not identify the 33-year-old man and did not say if he had been charged.The Wayne County prosecutors told CNN that that they have not yet received a police arrest warrant.
The three dogs have been brought to Detroit Animal Care and Control and are under investigation.
"Due to the severity of the case, this is a serious case likely to put the dogs to sleep." said the department in a statement.
"It just can not be real"

" It's hard for me not to cry, "Cpt. Russell Solano of the Detroit Police Department told CNN daughter WDIV. We're talking about a 9-year-old girl, that just played and is not here now. "
