FORT LAUDERDALE, Fla. (AP) _ A youth who killed a 6-year-old while imitating professional wrestlers was sentenced Friday to life in prison without parole after a judge refused to dismiss his first-degree murder conviction.

Broward County Judge Joel Lazarus imposed the mandatory sentence on 14-year-old Lionel Tate, calling the murder of Tiffany Eunick ``cold, callous and indescribably cruel.''

``The evidence of Lionel Tate's guilt is clear, obvious and indisputable,'' Lazarus said. ``And that evidence supports the jury's verdict.''

Tate's attorney Jim Lewis has said he will ask Gov. Jeb Bush to commute the sentence. Prosecutor Ken Padowitz urged the judge to uphold the first-degree murder conviction, reached by a jury Jan. 25 following a two-week trial, but said he will support the commutation request.

Padowitz will not say what sentence he believes Tate deserves. Before the trial Tate turned down a plea agreement that offered three years in prison, one year of house arrest and 10 years of probation. Lewis, Tate and his mother, Kathleen Grossett-Tate rejected that offer.

The prosecutor said at Friday's hearing that he would be willing to ask Bush ``to consider reducing to a sentence that is more appropriate for all the facts in this case, taking into consideration Tate's age at the time he committed the crime.''
