A fourth suspect in the brutal assault of a homeless man was arrested Friday.

Floyd Patterson, who goes by the name "Hulk," is the last of four suspects wanted in connection with the beating.

Robert Mohler, 49, was savagely beaten in the Penn Street Laundromat in the 900 block of Penn Street on Jan. 12.

Ana Ferrer-Reyes, Keith Darnell Allison and Irich Colon have already been arrested.

Mohler was found dead Feb. 5 in an industrial building in the 1200 block of Spruce Street in Reading.

Autopsy results will determine if his death was caused by the beating. Those results have not yet been released.
