A jury in Bryan has convicted a Tyler man on all five capital murder counts over a 1983 attack.
Darnell Hartsfield, 47, was accused in the abduction of five people from a Kentucky Fried Chicken restaurant in Kilgore. All were later found shot to death.
Prosecutors did not seek the death penalty, so Hartsfield gets an automatic life prison term.
The trial was moved from the East Texas town of Henderson to Bryan because of publicity about the long-unresolved case.
Hartsfield's cousin, Romeo Pinkerton, took a plea bargain a year ago midway through his own trial, agreeing to five life prison terms.
