William Elijah "Liam" Lyon, 18 months, passed away Monday after battling to survive being born with a left sided hypoplastic heart disease.
Liam received a heart transplant July 2011 after several other surgeries to correct his heart defect were unsuccessful.
Liam's followers on facebook posted more than 12,500 farewell messages.
District Judge Jon Sullivan has granted a motion filed by the LeFlore County District Attorney's Office asking for James Haskin Jr., 61, of Monroe, to submit a DNA sample.
According to the motion, evidence collected at the crime scene, where Haskin allegedly sexually abused multiple children, has been analyzed and confirmed as seminal fluids.
The DNA sample from Haskin will be used to determine if he is a match to the fluids.
Haskin is scheduled to appear in court next week.
