Galvan would allegedly hang out in public places until he spotted a woman he was interested in targeting. Then, he would check social media to see if she had checked in on Instagram, or posted a photo that had geotagged that particular location. If Galvan could find her there, he would allegedly go back through her photos and see if she had ever posted a photo from her home that also had its location data embedded. If successful, prosecutors say he would go to the woman's home and break in, then steal her electronics, jewelry, underwear and other personal belonging.3. Twitter's missing manual.
