OCALA, Fla. -

A north Florida man has been sentenced to life in prison for participating in a teen's slaying.

A Marion County judge sentenced 21-year-old Justin Soto on Wednesday after he pleaded guilty to first-degree murder.

Soto is one of five people accused in the April 2011 death of 15-year-old Seath Jackson.

Authorities say Jackson was lured to a Summerfield home, where he was beaten, tied up and shot. Arrest reports say Jackson's body was burned, and his remains were placed into buckets and tossed into a lime pit.

Still facing first-degree murder charges are 20-year-old Michael Bargo, 16-year-old Amber Wright and 17-year-old Kyle Hooper. Prosecutors are seeking the death penalty for Bargo, who authorities identified as the shooter.

The fifth suspect, 19-year-old Charlie Kay Ely, received a life sentence last fall.
