FORT LAUDERDALE, Fla. (AP) - A 16-year-old accused of stomping a middle school student in the head faces a maximum sentence of 50 years in prison.

Prosecutor Maria Schneider agreed Thursday to cap the maximum sentence for Wayne Treacy when he stands trial as an adult on attempted murder charges.

The case stalled partly because Treacy's lawyer says he didn't know how much prison time the boy faced due to a recent U.S. Supreme Court decision. The court ruled that anyone under 18 who commits a non-homicidal offense cannot be subjected to life in prison without parole.

Treacy is accused in the March 17 beating of Josie Lou Ratley at Deerfield Middle School. Now 16, Ratley was left brain damaged and is continuing rehabilitation at home.

Treacy's next hearing is scheduled for March 31.
