Teens Who Ruined Many Lives.

In 1999, Curtis Jones was barely out of elementary school when he was sent to prison. The Florida preteen was just 12 years old when he was convicted of killing his father's girlfriend. Now, at 29, Jones is leaving prison a grown man — and, seemingly, a changed one. Jones' murder case was chilling yet heartbreaking. When he was 12 years old, Jones and his 13-year-old sister, Catherine, fatally shot their father's girlfriend, Sonya Nicole Speights, in a plot to kill their family for alleged child abuse. The siblings were charged with first-degree murder, but eventually struck a deal, pleading guilty to second-degree murder. Curtis and his sister were sentenced to 18 years in prison, followed by a life on probation. www.bustle.com
