No, not necessarily.
Patrick Latko trial 2011:
""But while no DNA found matched Latko’s, Shill argued the circumstantial evidence links him to the deaths of the mother and son in their South Madison Avenue home."
"But not a drop of blood was found on Latko or his belongings, argued public defender Kevin Moses.
“So there were 20 stab wounds, two slit throats....so whoever did this would've been a bloody mess,” Moses said to the jury."

---------------
In closing arguments earlier Wednesday, the defense began by claiming that the evidence in the fatal stabbings did not directly implicate Latko, 33, in the deaths.
But while no DNA found matched Latko’s, Chief Assistant Prosecutor Cary Shill argued the circumstantial evidence links him to the deaths of the mother and son in their South Madison Avenue home.
Is Latko “the unluckiest guy in the world? Or did he kill Ryan and Diana Patterson?” Shill asked.
Public defender Kevin Moses pointed out that not a drop of blood was found on Latko or his belongings.
“So there were 20 stab wounds, two slit throats ... so whoever did this would've been a bloody mess,” Moses said to the jury.

(Latko was found guilty on solid evidence... but DNA at the scene or blood on him? No.)
Exactly the point: Latko was found guilty on solid evidence. You use him to make the point that it's possible to murder people and not leave DNA or other physical evidence. Granted! But it's not possible to convict someone without some other "solid evidence."
In the Latko case:
sourceThe evidence consisted of numerous text messages Latko had sent to friends including one which stated that if he finds out who was criticizing him to his former girlfriend,
“they’re a dead man.”
It included a knife that belonged to Latko which tested positive for Ryan Patterson’s blood, and Latko’s cell phone, which was found in the Patterson’s home following the murders. It included surveillance footage of Latko changing his clothes little more than one half-hour after the murders had occurred . . .
That's pretty compelling evidence, yes? Where is the similar evidence against either Amanda or Raffaele? She got a noise ticket for a loud party. She participated in an April Fool's day prank. She wrote a short story. He owned a pocket knife. He liked manga comics. He's known to have watched a porn movie.
If you don't have DNA, you need something better than the victim told her friends that the suspect didn't use the toilet brush often enough.
