Elvira and Tina are 95 and 80 years old, so they were probably very grateful to the young man outside the elevator who let them go in ahead. That's when things took a frightening turn. The young man began to rob the women, ripping away Tina's necklace. Elvira fought back but the robber threw her off and tossed Tina to the ground. Police have released the CCTV video, hoping someone identifies the suspect.
