OAKLAND — A 1-year-old baby struck by stray gunfire Saturday was released from the hospital and was playing at home Monday.

Prosperity Banks was one of three children hospitalized after being hit by gunfire Saturday while crossing International Boulevard at 64th Avenue. None of the children suffered life-threatening injuries, but a 4-year-old girl shot in the chest remained in a hospital Monday after surgery.

Prosperity had been riding in a stroller as her aunt, Laurice Blue, walked with an adult cousin and the 4-year-old.

"We went to the McDonald's at 65th (Avenue), and we were going to cross right there, but we had the kids with us, so we decided to go down to the crosswalk to be safe," said Blue, Prosperity's aunt. "Right then, no warning or nothing, we heard the shots. "... I didn't think. I couldn't. I just grabbed the stroller and ran carrying it to get away.

"Cars were swerving around us, and we're trying first not to get hit by a bullet and then not to get hit by a car."

The children were shot when one group of young men fired on another group walking nearby, police said. There were multiple shooters, and police have not ruled out the possibility that some of the intended targets were hit by gunfire but did not seek medical help.

One of the shooters was described as a 16- or 17-year-old black male, standing 6 feet tall and weighing about 150 pounds. He was described as having a gold tooth, long dreadlocks with gold tips, a mustache and a small amount of chin hair, police said. He was wearing dark clothing.

Mayor Ron Dellums released a statement Monday calling the shootings "senseless and tragic" and said the Police Department will conduct a thorough investigation into what happened.

On Monday afternoon, Prosperity returned home from the hospital and walked, danced and played with her mother, Princess Blue, who said the bullet that struck her daughter had produced six wounds but miraculously hadn't done any vital or permanent damage.

"She will walk, but she doesn't want to let anybody hold her hand," Blue said. "It's such a relief just to be able to be at home with her, but I'm still not all the way all right. I don't know what's going on around here still. "... They didn't shoot the people they were looking for, so are they coming back or what?"

The 4-year-old girl and a 14-year-old boy also were hit in Saturday's shootings.

The 4-year-old girl was shot in the chest and had to undergo surgery, police said.

Laurice Blue said that like Prosperity, the older girl had remained quiet and calm during the shooting, and that she would remain in the hospital for about a week, but that "she's talking, playing with toys. She's really hungry, so that's good, too."

The boy suffered superficial gunshot wounds and was released from the hospital Sunday.
