On August 14, 2023, in Reading, Pennsylvania, 14-year-old Tomas E. Medina Jr. fatally shot his father, 44-year-old Tomas Medina Sr., near their home in the 1100 block of Locust Street. The shooting happened about 3:45 p.m. after the family returned from a trip and an argument broke out; authorities say the teenager used his father’s firearm. Medina Jr. fled but was taken into custody shortly afterward and was charged as an adult with first- and third-degree murder, aggravated assault, and related offenses. Pennsylvania law allows no bail for first-degree murder, and he was held in custody. The case has rattled the Reading community and prompted discussion about family dynamics and youth violence.

What information about the days and hours before the shooting might help explain how the argument escalated to lethal violence?
