FT. MYERS, Fla.-The State Attorney's Office says because of his age, Yoel Munoz is not eligible for the death penalty. Instead he faces life in prison if convicted of this murder.

Eyes red from crying, Yoel Munoz's brother Lazaro answered the door at his family's home Wednesday, too upset to talk. Hours earlier a Lee County grand jury indicted his 13 year old brother on first degree murder and burglary charges for the death of 51 year old Thomas Bergstrom.

Cape Coral Police said Munoz walked into this homeless camp earlier this month, armed with a knife, and stabbed Bergstrom over and over, killing him. WINK News spoke with Anthony Cashdollar who said he found Bergstorm's body.

"I said Tommy, Tommy, Tommy like 4 or 5 times and that's when I finally realized Tom was dead."

Police tell WINK News a knife and face mask, covered with blood, were found at the scene. They also discovered more evidence inside Munoz's home, like blood smeared on clothes, walls, and his bed.

Munoz was moved from a juvenile detention facility into the Lee County Jail Wednesday afternoon.

Earlier this month, WINK News spoke with the teens family, who told us their son is innocent

"The truth is going to come out and he didn't do it. I am 100% sure of that."
