Chicago cops are asking witnesses to come forward with information about a possible serial killer who may be responsible for the deaths of more than 50 women, a report said Friday.

The Chicago Police Department said they are looking into the possibility of a serial killer after a group called the Murder Accountability Project concluded that there is a pattern in the slayings, according to CBS Chicago.

“This isn’t something we’re going to sweep under the rug or put up on the shelf for it to disappear,” superintendent of Chicago police Eddie Johnson told the network. “We still investigate these cases.”

The Murder Accountability Project said the pattern of the killings — 50 females strangled and their bodies dumped since 2001 — is consistent with a serial killer.

“It’s highly unlikely these 50 women were murdered by 50 separate men,” the head of the project, Thomas Hargrove, said.

Families of the victims have come forward to demand answers after the project released their findings.
