A brain was found in a bag near an apartment complex Tuesday morning, and the state medical examiner's office was trying to determine whether it was human or animal, police said.

The brain, or portion of a brain, was discovered in an area next to a suburban Richmond apartment complex under construction and near a mall, Richmond police spokeswoman Karla Peters said. She believed the people who discovered the organ were construction workers, but said she had not confirmed that information.

Police were called to the scene and the brain was turned over to the medical examiner's office, which will determine whether the brain once belonged to a human or an animal, Peters said.

Peters said she had no additional information.

"We're waiting for the medical examiner to determine how we should proceed," she said.
