Wallace testified that Delgado pulled a gun on him and the two struggled outside the car. He said he was forcing the gun away from himself when it went off and Delgado was shot.
Wallace was arrested in DeKalb County about five weeks after the shooting while riding in a car where several stolen guns, including the murder weapon, were found, according to the release. Ballistics testing matched one of the guns with the bullet recovered from Delgado’s head.
Wallace had a long criminal history in Gwinnett County, including five separate arrests between 2008 and 2011. He was charged with aggravated assault and armed robbery in 2008 and spent about 18 months in the Gwinnett County jail.
Gwinnett County Assistant District Attorney Nigel Lush prosecuted the murder case.
