Florida ? After hearing testimony from 13 witnesses over two days, a Broward County grand jury Thursday indicted three teenagers in the fatal beating of a homeless man and the baseball bat attacks of two others.

Each of the three teens is now charged in all three Fort Lauderdale beatings, and 17-year-old Thomas Daugherty will be tried as an adult.

The indictment charges Daugherty and Brian Hooks, 18, both of Plantation, and William “Billy” Ammons, 18, of Fort Lauderdale, with first-degree murder in the Jan. 12 beating of Norris Gaynor. The grand jury also upgraded charges in the beatings of Jacques Pierre and Raymond Perez to attempted first-degree murder.

Daugherty, ineligible for the death penalty under U.S. Supreme Court rulings, faces life in prison. Prosecutors have not decided whether to seek the death penalty against Hooks and Ammons.
