4 human skulls found in Chicago apartment

Four human skulls were discovered in a man's apartment, one boiling in a pot of water, but authorities said charges aren't likely.

"It doesn't seem to be anything nefarious at this time," police Lt. Perry Nigro said. The 26-year-old owner of the skulls makes anatomical models for a living and appeared to be using them for medical purposes, Nigro said.

"As weird as it is, it doesn't seem like anything is wrong," Nigro said.

Police searched the apartment after someone who wanted to buy a mannequin in the home visited late Tuesday and saw the skulls on a porch and inside, with one boiling on the stove.

The skulls' owner told authorities that he imported them legally from China.
