Overview
- Cobb County Judge Sonja N. Brown convicted Matthew Scott Lanz on all counts after he waived a jury, with sentencing scheduled for 10 a.m. Friday.
- Prosecutors presented DNA links, firearm analysis, and surveillance video placing Lanz around the Hicks’ home on the night of the shootings.
- The couple’s 2‑year‑old son was discovered the next morning covered in blood, and the indictment alleges he was left alone for about 12 hours.
- Lanz was arrested the day after the killings following an alleged Sandy Springs break‑in during which a police officer was stabbed and another officer shot and wounded him.
- The defense highlighted schizophrenia and delusional beliefs, but the court had previously found Lanz competent to stand trial, and testimony referenced prior family violence including his brother’s fatal Pentagon attack.
