Chien-Kuo Lin, 67, was found dead in the garage of a two-story home on South Sixth Street in North Wales, a Philadelphia suburb, on a Sunday afternoon in May 2016. He died of a single gunshot wound to the chest after visiting his ex-wife’s home to retrieve belongings. Concerned enough to ask a police officer to accompany him, the officer left less than half an hour before the shooting.

Responding officers found 63-year-old Hsiu-Chin Linda Lin sitting at the kitchen table with a .38 caliber revolver in front of her. According to reports, in the week before the incident she had been practicing firing the weapon in her backyard. On the day of the shooting she allegedly emerged from the house with the gun while their adult son was moving boxes, asked him if he would blame her if she killed his father, and called her daughter saying she was going to kill him. After gunshots rang out, she told their son to call 911.

Prosecutors linked a possible motive to a family business dispute and to Lin living with another woman. If anyone knew the family, witnessed tensions around that time, or has information that could help, please share what is known.
