"I want to see this person's face," Diena Thompson told ABC's Good Morning America. "I want them to get the death penalty. I have to be the voice for Somer."
The child's remains were found last October in a south Georgia landfill, days after she disappeared while walking home from school in the Jacksonville, Fla. suburb of Orange Park. Authorities last Thursday arrested Jarred Mitchell Harrell, a former neighbor of the Thompsons, on dozens of counts of child pornography, calling him a person of interest in the case.

Diena Thompson told ABC, she needs to know the truth about what happened to her daughter, saying,"I've built up so many scenarios in my head, that I honestly don't feel like anything they could tell me could be any worse than what I've already made up in my head."

Thompson's attorney, Michael Freed, said his client is optimistic the arrest will help bring closure to the case, but doesn't want to overreact prematurely.
Harrell has not been charged with murder.
7-year-old Somer Thompson used to stop at Harrell's house walking home from school to pet a white dog.
"I still blame myself, you know?, said Thompson. What if I did this? Or what if this could have been done and instead of looking in the mirror and blaming myself, I'm going to have a picture of someone else to blame," she said.
Harrell left his computer behind when he moved out of the Orange Park neighborhood. His roommates turned the computer over to the Jacksonville Sheriff's Office after claiming to find child pornography on it.
Harrell was arrested in Meridien, Miss. on 29 counts of child pornography, and was being held on $1 million bond.
