On February 1, 2008, Tamara Ruth Tammy Waggoner Browning, 44, was found shot to death in her Cockeysville, Maryland, home alongside her husband, John W. Browning, 45, and their two younger sons, Gregory, 13, and Benjamin, 11.

Investigators took the family’s eldest son, 15-year-old Nicholas Waggoner Browning, into custody on February 3, 2008. He was charged as an adult with four counts of first-degree murder; prosecutors said he returned home in the night, used his father’s gun, then went back to a friend’s house to establish an alibi. Nicholas later told the court he had been abused by his father and cited that as his motive, while the prosecution said the killings were premeditated and connected to a desire to escape parental rules and access an inheritance. In January 2009 he pleaded guilty and received four life terms, two to be served consecutively.

Did anyone in Cockeysville at the time notice unusual behavior from the family in the days before February 1, 2008?
