DOUGLASVILLE, Ga. - Two men have been found guilty in the beating death of a teen who was attacked outside a house party in November of 2010.

Quantez Mallory and Horace Coleman are set to be sentenced for their roles in the death of 18-year-old Bobby Tillman on Feb. 4.

Four men were involved in the teen's death and two have already been sentenced to life in prison.

Emanuel Boykins told prosecutors he started the unprovoked attack, which led to three others eventually jumping in. He pleaded guilty to murder in April.

Tracen Franklin - a former student at Alabama State University - was sentenced in September to life in prison without the possibility of parole for his role in the teen's death.

Douglasville is about 25 miles west of Atlanta.
