Testimony began Wednesday in Tracen Franklin's capital murder trial, WSB-TV reported.
Franklin is accused -- along with three others -- of stomping to death Bobby Tillman, a Douglas County teenager, outside a house party in November 2010. One suspect has already pleaded guilty and the other two will as well, WSB's report said.
WSB reported Frankin's attorney, Bruce Harvey, did not deny Franklin's involvement in the beating, but he is trying to convince jurors that the beating was not "premeditated or planned" in an effort to avoid the death penalty.
Testimony will continue Thursday.
