"This will be the last breath that I waste or use on you," Thompson said before leaving the witness stand. "As with the last breath, I would like to tell this honorable court that it is now time to take out the trash. May God have mercy on your sorry, sorry soul."
Before speaking, Thompson walked to the stand with Somer's twin brother, Samuel, who also made a brief statement.
"We know you did this. We have evidence. She trusted you, but you had to do what you did, and look where it got you, and now you're going to jail," he said, staring down Harrell.
Other relatives of Somer's also spoke in court.
"Your selfish actions have forever changed so many lives," Somer's aunt, Dawn Burner, said to Harrell in impact statements. "Knowing you will never be able to hurt anyone else again is the only peace I get from this senseless act you have committed."
"Do you know what you did to my family on Oct. 19, 2009? You took everything," Debbie Bowling, Somer's grandmother, said while crying. "How could you? ... How could you kill a defenseless little 7-year-old girl that only loved everybody?"
She said Somer's twin and other siblings all took the blame for something Harrell did.
"You are no longer a person or a gentle giant. You are a monster, and you should be treated so," she added. "Do you know where they put monsters? They go to big boy prison, and I hope the prison system will show you a real good time like you did Somer."
"I don't even know how you can live with yourself," Somer's older sister, Abi Thompson, told Harrell. "You're not even a human being. Your name is not Jarred Harrell. Your name is monster."
Recalling road to justice for Somer
Within hours after Somer's kidnapping was reported more than two years ago, hundreds of people -- many who had never met the girl -- joined the search. By the time her body was found, thousands who had never met Somer felt the loss.
The investigation into who killed Somer was frustratingly slow, but the Sheriff's Office was persistent.
On Feb. 11, 2010, Harrell, a former Orange Park resident, was arrested in Meridian, Miss., on 29 charges of possession of child pornography and was named a person of interest in the case.
That same day, Clay County detectives and the Florida Department of Law Enforcement searched a house in the 1100 block of Gano Avenue, not far from where Somer lived.
On March 26, 2010, Harrell was charged with murder in Somer's death.
Investigators said they found child pornography on a computer that belonged to Harrell, which led them to him. They found out he lived near Somer's home in Orange Park. Eventually, investigators found him at a relative's house in Mississippi.
Details of the case have been under tight guard with a gag order in place. The gag order was removed after the guilty plea.
