Given the severity of the news, Susan and Diane decided they had to get ahold of the women Philippe had dated and stop him from infecting others. They filed a police report and launched their own full-scale investigation, starting with Philippe's cell phone records. "We contacted somewhere between 23 and 26 women," Diane says.
One of the women Diane found was Megan, who lived across the street from Philippe and dated him for more than two years. She says she had already suspected him of cheating and broken up with him by the time she got the phone call.
Megan learned she was also infected with HIV and joined the crusade to stop Philippe. "I mainly used the window to watch cars coming in and out and to watch what was going on at Philippe's house or which women were coming in and out," she says. Megan says she stopped women who were leaving Philippe's house to warn them that their lives could be at risk.
Together, the three women took down license plates and followed Philippe for at least six months.
