CHOP doc murder suspect: Is he also the...

Philadelphia police want to know if the CHOP doc murder suspect Jason T. Smith is also the Pennypack and Fairmount Park rapist they have been seeking according to NBCPhiladelphia.com on Friday.

Jason Smith looks a lot like the two rape suspect images sketched by a crime artist. But why are police suspecting him of raping women in two parks if he didn't rape Melissa Ketunuti? That's simple. The fact that he has confessed to the murder crime of Melissa Ketunuti does not mean that his statements about what happened with her that day are true.

Any man capable of binding, strangling and murdering a woman who he had just met is certainly capable of lying about why he did itÂ—and what really happened that day that he did.

The medical examiner will be able to paint the true physical picture of events, including whether the children's pediatrician was sexually assaulted or not. So it is likely that the police are being thorough and running Smith's DNA through the state and federal criminal databanks to see if they get a hit on any other unsolved crimes, like that of the Pennypack Park suspect pictured above.

And if the autopsy revealed Ketunuti was sexually assaulted, then that would motivate them to consider Smith for other unsolved sex attacks in their city.

The CHOP doc murder case details definitely have sexual overtones to them, with the tying up of the female in a hogtied fashion, for example. That was so unnecessary to the commission of the crime of burning her body. Yet the CHOP doc murder suspect did it anyway. Then there is also the fact that she was strangled, which is a very sexual type offense if you ask Roy Hazelwood, formerly of the FBI and the author of such books as "The Evil That Men Do: FBI Profiler Roy Hazelwood's Journey Into the Minds of Sexual Predators."

And although police have repeatedly said during the course of their investigation this week that they don't think sexual assault occurred in the Philadelphia doctor's murder, they've only been working this case for less than a week. So they didn't have autopsy findings at first to tell them for sure if she had been sexually assaulted or not. And even if she were not, that does not mean he wasn't planning to do that to her, but that he maybe didn't get the chance first.

In the Fairmount Park rape case, the rapist is believed to have been Hispanic, as pictured in the sketch to the right, but that detail could be inaccurate, so Smith can't be discounted just on that piece of information.

And in the Pennypack Park rape case the suspect drove a truck, but Jason T. Smith can't be accused of those rapes just because he drives a truck. However, it does show that he and that rapist had a similar method of transporation that they used. And if DNA were to tie him to those cases that would be important.

Philadelphia police say that DNA will help them decide if Jason Smith could have been the rapist they've been searching for in Fairmount Park, where four women were raped, or if he was the rapist in Pennypack Park, where three women have been raped. Neither rape case has been solved, with the cases beginning in April of 2003, in Fairmount Park, and the most recent one happening in July 2012, in Pennypack Park.
