Investigators also looked into whether or not a serial killer or pedophile was on the loose hurting children. Someone had even called up Glover to tell her that Shane was buried in an abandoned building. However, the police couldn't find anything in their investigation. They also ruled out ransom as a motive, as no one contacted the families for money.
There's a murder that's often been analysed alongside Christopher and Shane's cases. Before Christopher and Shane went missing, six-week-old Andre Bryant also disappeared from the Brooklyn area in March of 1989. Monique Rivera, his mother, was found slain in the Bronx after going on a shopping trip with two women she apparently knew from middle school. The women insisted she bring Andre, her youngest son. He was never seen again. If the assailant went after Andre, could they have gone after the other boys? The connection is a little tenuous, but it's not completely outside the realm of possibility.
