In the past two years, one in five Texans has been a victim of stalking, according to a survey by the Crime Victims' Institute of Sam Houston State University. 

With technology advances, stalkers have found new ways to harass and violate their victims.

"Today stalking is facilitated by cell phones, text messages and e-mail, by those who want to keep track of their boyfriends or girlfriends, often at a very early age," said Laura Zarate, executive director of Arte Sana, an organization dedicated to helping underserved survivors of racial- and gender-based violence.

"We can usually tell if someone is following us home," said Texas first lady Anita Perry. "But we can't usually tell if someone is using spyware to monitor our computer or if someone is using a GPS system planted on our car to track our location."
