TAMPA, Fla. — Ninety murders.

That's how many women investigators say Samuel Little has claimed to have killed from the 1970s to 2013.

And some of them happened in Florida.

Prosecutors in Los Angeles used DNA in 2014 to convict Little of killing three women there in the late 1980s. Little claimed he was innocent.

But this spring, investigators said he started confessing, providing dates and locations of killings from coast to coast — a decades-long trail of beatings and strangulations.

Two days ago he was in court in Odessa County, Texas, where authorities say they have linked him to a killing.

And in Marion County, Florida, investigators say Little confessed to killing a woman named Rosie Hill.

"I've taken a lot of confessions from a lot of murderers, but this was my first serial killer of this magnitude," said Sgt. Michael Mongeluzzo of the Marion County Sheriff's Office.

"It was sitting with pure evil in a grandfather's body, if you will. He's in a wheelchair and he's killed all these people. So in one breath you want to trust him and give him a hug, and in the next breath you don't want to turn your back on him because of what he is capable of."

Two of his confessions have connections to the Bay area — one in Plant City and another in Tampa.

Tampa Police Spokesman Steve Hegarty said the TPD has been talking to the Federal Bureau of Investigation and other agencies about Tampa cold cases.

"Do we have cold cases from that time? Yes we do," he said.

"Now Mr. Little, from what I have read, has been very detailed about some of the murders that he has talked about, which is very convincing to some other jurisdictions," he said. "I don't know that we have the kind of detail we need to definitively connect him to one of our cases."

Details on a possible Samuel Little murder in Tampa may not be too solid now, but police said it's a start.

"Absolutely, and that's why we are going to pursue it until there is nothing left to pursue," Hegarty said.

Plant City Police say they don't appear to have any cold cases from when Little made his claims but is reviewing files to see if it can help in the investigation.

Little is being held in an Ector County, Texas jail.
