Not sure this has been posted on here but there was an article from April this year on the case which featured interviews with the two women who were assaulted by this creep on the clothing store featured on UM.

Those poor women (and his other victims). I hope their cases can be solved after all this time.

The statute of limitations on the rapes have expired.
