NEW ALBANY, Ind. (WDRB) -- The southern Indiana man convicted of killing and dismembering an elderly woman pleaded guilty to second degree murder Thursday.

Gibson returned to court to change his plea as expected, but what took most by surprise is the new tattoo he has on his head that reads "death row X 3."

"I don't try to figure out what's going on in his mind," said Floyd County prosecutor Keith Henderson, when asked why the convicted killer showed up to court with the new tattoo.

With cameras not allowed in the courtroom - we aren't able to show it to you.

The picture on the right is similar to what it looks like.

"That has been addressed by the court. That will be an issue for a trial. To the best of my knowledge, even though I haven't seen it in writing, the judge has ordered him to be withheld from haircuts so that will be covered up," said Henderson.

"He seemed like he had a purpose for getting it. As far as proud, he just seemed like he had a purpose for why he received it," said Major Andrew Sands with the Floyd County Jail.

In court Thursday, Gibson admitted to the 2002 murder of 45-year-old Karen Hodella.

He received a 65-year prison sentence.

Gibson was transferred to Floyd County from the State Department of Corrections for the plea deal hearing.

In Oct. 2013, Gibson was convicted of the murder of 75-year old Christine Whitis and received the death sentence.

He still faces a third murder charge.

In June, he is scheduled to go to trial for the murder of 35-year-old Stephanie Kirk of Charlestown.

Her father tells WDRB's Tamara Evans that he doesn't want to see Gibson take a plea deal - and would rather see him pay for what he did, and face a jury.

That upcoming trial is the reason the new head tattoo is causing such a stir.

"It potentially affects the prosecution of a very important case and quite frankly, I think there needs to be some sort of explanation from the Department of Corrections on how that can occur when somebody's on death row," Henderson told WDRB.

But there's still some confusion as to where or when he got it.

"Based on statements from the jailers here, we don't believe it occurred here and I intend on taking that up with the Department of Corrections," said Henderson.

"He was held at high security risk and maximum security while in my facility. We know the tattooing didn't occur here," Sheriff Darrell Mills of Floyd County told media Thursday.

The Indiana Department of Corrections tells WDRB they have no record of Gibson having that tattoo when he got to their facility.

Communications officials there say a prisoner can be charged with a misconduct violation if they do get a tattoo inside the facility.

They do say while in the Floyd County Jail, he has threatened staff members.

"He basically would just threaten them with their lives. He had nothing to lose he would say. So, it was not that he was gonna harm them. He was gonna kill them," said Sheriff Darrell Mills.

Gibson is scheduled to go to trial for the murder of 35-year-old Stephanie Kirk of Charlestown, Ind. on June 2. That trial is set to happen in Vanderburgh County.
