When the female owner of the pet shop was taken back for questioning by the police, she claimed that the deceased owed money and had stolen gold jewelry. However, according to police investigation, the pet shop used various pretexts to deduct employees' salaries and imposed fines for trivial things, such as not cleaning the floor thoroughly, not smiling at customers, and not getting along well with colleagues. In just over 20 days, more than 400,000 NTD in fines were accumulated.
