On the morning of December 15, 2014, a deadly attack spanning three homes in Montgomery County, Pennsylvania, ended with multiple members of one extended family killed. Jo Anne Koder Hill, 57, of Lansdale, was killed at her home when her former son-in-law forced his way into several residences during a violent rampage tied to a custody dispute.

The attacker, identified as 35-year-old Bradley William Stone, targeted his ex-wife Nicole Hill and her relatives. Stone’s actions also claimed the lives of Patricia Hill (Jo Anne’s mother), Nicole Hill, Patricia Flick, Aaron Flick, and 14-year-old Nina Flick; a 17-year-old, Anthony Flick, survived with serious injuries. Stone was the focus of a large manhunt that prompted shelter-in-place warnings for local residents.

Stone’s body was later found in woods near his Pennsburg home; authorities determined he died by suicide from self-inflicted cutting wounds. The investigation cited the ongoing custody fight over Stone and Nicole’s two young daughters as the primary motive.

Did anyone in the area know Jo Anne Koder Hill or the family and have information that could shed more light on what happened that day?
