BRUNSWICK — A Georgia man was convicted of murder Friday in the beating deaths of his father and seven extended family members inside the cramped mobile they all shared, but he was spared a death sentence in a deal attorneys made to avoid a hung jury. Guy Heinze Jr., 26, stood silently while his younger brother ran cursing from the courtroom after the jury's verdict was read. The last-minute deal to withdraw the death penalty means Heinze will be sentenced to life in prison.
