Alaysha Carradine was fatally shot while on a sleepover at her best friend's house on the 3400 block of Wilson Avenue. Carradine's best friend, who is 7-years-old, was also shot. The friend's grandmother and 4-year-old brother were shot as well. The two kids and the grandmother are in stable condition at the hospital.
Khamel Hardin, 22, was also home; the two kids who survived the attack are his niece and nephew.
"It sounded like firecrackers, like an explosion or something like that, or a bomb. But they said it was gunshots," said Hardin.
Hardin said the killer rang the doorbell and his niece answered the door. Hardin said he did not get a good look at the gunman and has no idea why anyone would target his family.
"I don't know who they were aiming for. He was probably aiming for somebody else," said Hardin.
Carradine was nicknamed 'ladybug' by her family. She was going into the third grade. Jesse Fowler, who is Carradine's stepfather, said she was a very bright girl.
"It's a shocker to me. It hit me earlier at the hospital. I'm still in denial that she is really gone. I'm used to her talking my ear off and she is not going to be there anymore. She has a younger brother who I have to raise without her now, so this is going to be difficult," said Fowler.
Fowler said his stepdaughter asked him to walk her to the door yesterday.
"I said, 'Do you need me to walk you to the door? Are you not too big for that?' She said 'no' and I said, 'OK, I'll walk you to the door.' I think that was probably the last thing I probably said to her," said Fowler.
Fowler says the girl's mother was out of town on business and she flew back Thursday evening.
"She doesn't want to accept the fact that she's gone. And I really understand that and I think that was probably the hardest thing for me to do was to break the news to her," said Fowler.
"They thought it was their mom coming home. That's what they thought. I'm sure that's what they thought. That's why all three of them were at the door," said Sharon Smith, Alaysha's step-grandmother.
The mother of the two kids who live at the home works at Children's Hospital Oakland and on Thursday night she was there visiting them.
This murder has so many members of the community outraged. That's why Oscar Grant's mother came to the neighborhood where the children were shot. The police chief even showed up on Thursday night to pass out fliers about a $25,000 reward for information, he hopes will lead to an arrest.
"It's senseless to kill a young baby. She hasn't even lived in the world," said Wanda Johnson, Oscar Grant's mother.
But when neighbors heard a few anarchists were planning to march near the scene of the shooting, they were quickly uninvited.
"Get out! This is not for you. Not right now!" yelled one neighbor at an anarchist.
The police chief showed up to talk to neighbors.
"We do have some leads, but this is one that witnesses are going to be key in," said Oakland Police Chief Sean Whent.
There is a mobile police command center in the neighborhood and investigators say they're determined to solve this case. Police have not made any arrests so far and they do not have a description of the killer or a motive for the shooting.
