On February 1, 2008, the Browning family of Cockeysville, Maryland, was found shot to death in their home. John Browning, 45, an attorney, was located in a ground-floor room; his wife Tamara, 44, and their younger sons Gregory, 13, and Benjamin, 11, were discovered in upstairs bedrooms.

Investigators quickly focused on the family’s eldest son, 15-year-old Nicholas Waggoner Browning. Police say Nicholas used his father’s handgun after the family went to sleep, shot each of them, discarded the weapon in nearby bushes, and spent the night and next day with friends. He was arrested on February 3, 2008, and confessed to the killings. Prosecutors described alleged motives tied to a desire for freedom from parental rules and inheritance; Nicholas alleged abuse by his father.
