MILWAUKEE -- A memorial with balloons and teddy bears is growing outside a house on Milwaukee's north side.
The victim was identified by police Sunday morning as Miyanna D. Jelks.
"She was a beautiful, young girl. She was smart, intelligent. She was just 9 years old," said Jay Jones, a family friend.
Jones said seven children live in the house with their mom and dad and he doesn't believe the father knew their was a gun inside the house.
"They are not the type of people to put their kids in no type of danger or anything like that," he said.
Police say the brother is a minor and was taken to Milwaukee County Children's Court Center.
Police say the girl's parents, a 29-year-old Milwaukee woman and a 32-year-old Milwaukee man, were arrested on multiple charges.
Police will present the case to the Milwaukee County district attorney's office in the coming days.
