The chimpanzee habitat at the Los Angeles Zoo was open for visitors Wednesday, a day after a baby chimp was killed by an adult male in front of dozens of visitors.

The baby's mother, Gracie, was allowed to keep the chimp's body after Tuesday afternoon's attack. Zookeepers will decide how long she keeps it, said spokesman Jason Jacobs. He said he didn't know what would happen to the baby's body after it was taken from the mother.

The infant was the first chimpanzee born at the zoo since 1999.

There are 13 chimpanzees left at the zoo. The unnamed infant was born March 6 and had been gradually introduced to the troop, one of the largest in a North American zoo. There were no aggressive signs, Jacobs said, but it is common in the wild for males to kill the offspring of females they are interested in.

Jane Goodall started studying chimpanzees in the wild in Gombe National Park in Africa nearly a half century ago, said Stephen Zawistowski, executive vice president for national programs and science adviser for The American Society for the Prevention of Cruelty to Animals.
