Theresa Smith, 26, of Penn Hills, Pennsylvania, was shot and killed on September 5, 2014, outside Allegheny Auto Body on Verona Road. She was found with a gunshot wound to the head, taken to Forbes Regional Hospital, and died shortly after arrival. Theresa was three months pregnant and the mother of two boys, ages 5 and 8.

Police say the shooter was her boyfriend’s father, 58-year-old William Lieberth Sr. After the shooting he walked behind the shop and shot himself; he died in hospital two days later. Investigators reported there had been a disagreement between Theresa and Lieberth, though the exact nature of that dispute was not immediately clear. Theresa’s family described her as a loving mother who did not argue, and her funeral was held September 11, 2014.

Anyone who knew Theresa, her movements that afternoon, or who has information about what led to the shooting is asked to come forward.
