Attorney John Ray, who reps the families of slain Shannan Gilbert and Jessica Taylor, claims Rex Heuermann was not a solo operator and allegedly killed 3 prostitutes on Long Island with help from a mysterious cohort. Police have not linked the Gilbert and Taylor slayings to Heuermann as of now.

Ray pointed to the 2011 death of a 10-month-old baby girl whose body was found swaddled in a blanket near one of the confirmed Gilgo Beach victims. The lawyer insisted that a savage murderer would not have such maternal instincts to wrap the infant in a quilt.

"It's that kind of thing that, if you're such a depraved murderer, you don't take time to do. That to me seems like an act of a mother," Ray said, adding, "We also believe that some of the victims could've been lured by a woman."

Suffolk County Police officials have not commented on Ray's accusations on whether Heuermann had a cohort or if he's being eyed for the baby's murder.

But, Heuermann has enough legal problems to keep him busy. Detectives arrested him last week as he walked from his office in NYC, where he worked as an architect.

Prosecutors charged Heuermann with the murders of three sex workers and he's the top suspect in a fourth slaying. Heuermann allegedly wrapped their bodies in burlap and dumped them near Gilgo Beach between 2009 and 2015.

According to court documents, Heuermann was connected to the crimes through DNA testing and examining his cell phone records.
