I read this weekend’s New York Times profile of Roy Den Hollander, the lawyer who law enforcement officials have identified as the shooter in the tragic killing of the 20-year old son of a federal judge, with an equal mix of horror and concern.

Den Hollander’s body was found in a rental car on a rural road in New York’s Catskills after an apparent suicide the day after the violent July 19 attack at the home of U.S. District Judge Esther Salas in North Brunswick, New Jersey. Officials say Hollander wore a Federal Express uniform as he shot and killed Salas’ 20-year-old son, Daniel Anderl, and shot her husband, attorney Mark Anderl, leaving him in critical condition. Salas, who was in the home’s basement at the time, wasn’t physically harmed.
