NORTH PORT, Florida (AP) - Twenty years after a brutal killing spree that terrified residents of North Port and Port Charlotte, prosecutors say they are ready to make their case against a man who confessed to the six slayings.

The Herald Tribune reports that Jeremy Bruce Sly will appear Wednesday in Charlotte County Circuit Court.

The 41-year-old Sly is serving a life sentence in state prison for a different murder. The new charge in Sarasota County is four counts of second-degree murder and a charge of aggravated battery with a deadly weapon. Charlotte County deputies previously booked Sly into jail there when prosecutors filed homicide charges as well.

The charges stem from the slayings of a retired couple in Port Charlotte and a North Port family with children on the same night in 1991.
