This security agency utilizes illegal aliens that are in the United States. Primarily of Nigerian descent. They have a Security guard working for them since 2004. This guard obtained the job utilizing his mother's name and ss#. Semper was notified of this because this same guard was working at a facility that I worked at and he was constantly pressuring the women to marry him because his visa had run out. Semper removed him for awhile. When Semper learned I had left my job at the same facility, they then hired him back (if he was ever fired) and now he's working under another fake name- "Mr. Amoh-Addo Nana". This guard also works for Tully House in Newark, NJ (Correctional half-way house) under this fake name and ss# and now he has applied for a gun permit through Tully House. He scored an 87 on the exam. He is not even supposed to be in this country and this security company know it.. When I called and told them yet again, I was told the owner said for me to do whatever.
