Jury selection is underway in Seneca County in the trial of three people charged with gang assault.
William Meacham, Stephanie Meacham and Marvin Snyder face charges in the September 2008 attack of Adrian Porter, 35.
The alleged attack took place at Hunters Run Townhouses on Peterman Road in Seneca Falls.
Porter's family believes the attack was in retaliation for Porter posting signs alerting residents to convicted sex offenders in the area.
Three others were charged in the attack.
Under a plea agreement, Brandon and Justin Meacham will testify in the trial and face misdemeanor charges instead of the felony gang assault charge.
Angela Wheeler pleaded guilty to attempted assault. It is uncertain whether she will testify in the trial.
If convicted of gang assault, Stephanie and William Meacham and Marvin Snyder could face five to 25 years in prison.
