State prosecutors played a chilling tape in court of a 13-year-old confessing to using a purple-handled kitchen knife to slash his mother’s throat as she slept — while his 2-week old sister lay nestled nearby in her crib.
"I woke up, I grabbed one of the kitchen knives and I went to her room.I killed her," Derek Rosa, 13, of Florida, who killed his mother Irina Garcia, told detectives.
A young Hialeah teen accused of the brutal stabbing death of his mother three weeks ago pleaded not guilty to the murder charge Tuesday and will remain in an adult jail — at least for the time being.
