A teenager prominently mentioned as a suspect in the slayings of five Florida college students is going on trial in the alleged beating of his grandmother, not for murder, a judge reminded jurors.

The five-man, one-woman jury selected Monday in the assault trial of Edward Lewis Humphrey was scheduled to hear opening arguments in the case today.Humphrey, 19, is accused of beating his 79-year-old grandmother, Elna Hlavaty, shortly after he arrived at her Indialantic home on Aug. 30 from Gainesville.

He had gone to Gainesville five days before to attend classes at the University of Florida. During the time he was there, five students - four females and a male - were stabbed to death in their off-campus apartments.

No one has been charged in connection with those crimes, but police say Humphrey is one of several possible suspects.

Circuit Judge Theron A. Yawn reminded jurors Monday that Humphrey was only on trial in his courtroom for the Brevard County assault charge.

Hlavaty, who is listed as a prosecution witness, recanted her initial allegations, saying instead that she accidentally fell and was not attacked by her grandson.
