Jurors Hear 'Hiccup Girl' Jennifer Mee's Jailhouse Confession in Murder Trial

Sept. 20, 2013— -- Prosecutors played a jailhouse call in the murder trial of Jennifer Mee, known as the "Hiccup Girl," where she is heard telling her mother that she "didn't kill nobody" but she "set everything up."

Mee, 22, who gained national fame when she was 15 years old because her hiccups lasted for five straight weeks, is charged with first-degree murder in the 2010 death of Shannon Griffin.

On Thursday, prosecutors played a jailhouse recording for the jury where Mee's mother asks her why she has been arrested and charged.

"I didn't kill nobody," Mee said. "…I set everything up. It all went wrong, Mom. It [expletive] just went downhill after everything happened, Mom."

Prosecutors allege that in 2010, Mee met Griffin and lured him to a home in home in St. Petersburg, Fla., to be robbed. Griffin struggled with two accomplices who then shot him four times in the chest, according to prosecutors.

At issue is whether Mee was a bystander or if she planned the robbery that ended in Griffin's death.

Police had previously said they did not believe Mee pulled the trigger. However, under Florida law her involvement in a robbery that led to a homicide makes her subject to a first-degree murder charge.

Although Mee pleaded not guilty, prosecutors previously turned down her lawyer's plea deal of a 15-year prison sentence.

On Wednesday, Mee's attorney told the court her client was a schizophrenic. The judge then ordered Mee to undergo psychological evaluation. It was later determined Mee is competent to stand trial.

Experts also testified that Mee's DNA was found on the victim's shirt. Though, the defense argued it could have been transferred to the shirt by another person, and a crime lab DNA expert agreed.

One alleged accomplice, LaRon Raiford, was convicted and sentenced in August to life in prison, while another co-defendant, Lamont Newton, has not yet gone to trial.

Mee made national headlines in 2007 when she hiccupped virtually non-stop for more than a month, up to 50 times a minute. The hiccups ultimately stopped, her family has said, because she was treated with drugs used to treat Tourette syndrome.
