Neighbors told FOX 32 they were shocked by the early morning police activity in their quiet area outside of Crystal Lake known as Prairie Ridge.

Lynne Leon lives three doors down and says she heard nothing overnight but woke up to police at her door.

"You always hear people say ‘I never thought it would happen in our neighborhood’…and those are the words that came to my mind," said Leon.

She says she mostly saw middle-aged women at the house, but knew there were others living there.

"I didn’t realize that a man lived there I only saw the ladies and there was at least two, but I think more than that," said Leon.

Her friend who lives next door to the crime scene woke up overnight to commotion.

"He opened his garage door to come out and that’s when the police yelled at him to get back in and close the garage door," said Leon.

The Sheriff's office said this was an isolated incident and there is no threat to the public. They expect to provide further updates as the investigation is in the "very early stages."

The coroner's office will complete perform autopsies Thursday afternoon. 

The Major Investigation Assistance Team is investigating alongside the Sheriff's office.
