INDIAN HEAD PARK, Ill. (AP) — Prosecutors say the man charged in the stabbing death of a 14-year-old suburban Chicago girl kept the teen's cell phone after the attack and used it to send "taunting and disturbing" messages to her family.

Cook County State's Attorney Anita Alvarez says 38-year-old John Wilson Jr. has been charged with first-degree murder and residential burglary in the death of Kelli O'Laughlin last week.

Alvarez says O'Laughlin came home from school to find Wilson burglarizing her family's home in Indian Head Park. She was stabbed in the back, neck and chest.

Alvarez contends Wilson used a rock placed inside a knit cap to break a window on the home. She says DNA evidence from that hat helped lead investigators to Wilson.

A judge on Friday ordered Wilson held without bond.
