DNA evidence from the crime scene indicates that the man who strangled Toronto transgender sex worker Cassandra Do also raped another sex worker (a genetic female) in 1997. The 1997 rape victim was able to provide a detailed description of her attacker. That?s great, because now the police have a lot to go on in tracking down the murderer. But you have to wonder if Cassandra Do would be alive today if the police had bothered to go after this guy in 1997. Of course, he might have served his prison term and been back on the streets by now if they?d caught him back then.
