BROWARD COUNTY, Fla. -- While Lionel Tate's case continues to take new twists and turns, the Florida Highway Patrol has reprimanded his mother for not keeping track of her service revolver.

FHP Public Information Officer Larry Googin said that Katherine Grossett-Tate was reprimanded for failure to report that her .40-caliber Beretta was missing. The disappearance of the gun was discovered when her son, convicted killer Lionel Tate, was charged with armed robbery in March 2005.

Since it was Grossett-Tate's first violation of policy, she received only a verbal reprimand.

The Beretta is one of three missing weapons that belong to FHP and that were in Grossett-Tate's possession.

Lionel Tate Refuses To Talk To Psychologist

Lionel Tate's attorney, Ellis Rubin, requested that Tate be evaluated after Tate wrote a letter to the judge last week asking to change his guilty plea in his probation violation case. Tate is accused of violating probation by committing the armed robbery of a pizza deliveryman in 2004. Ellis said the letter was written without his knowledge and proved that his client is not thinking rationally.

Tate is supposed to be undergoing a court-ordered psychological evaluation, but Local 10 has learned that over the weekend, Lionel Tate refused to speak to one of the two psychologists the court chose to interview him to determine his mental competency.

Tate's previous guilty plea would have spared him a possible life sentence. He has already admitted to possession of a firearm, and could face life in prison for that admission alone. His plea deal would have earned him seven to 10 years in prison.

Rubin said that he will meet with the judge Wednesday to determine how to proceed.

He is on probation for the 1999 death of 6-year-old Tiffany Eunick when he was only 12. He was the youngest person in modern U.S. history to receive a life sentence.
