Man Charged With Using Social Media to Burglarize College Students

If you tag your location on social media or post about your home or plans, police say you could be making yourself vulnerable to theft.

A college maintenance worker in California accused of sneaking into the rooms of 33 female college students and swiping their laptops, jewelry and underwear, targeted the women from their open, public posts on social media, police say.

“He was able to openly browse the different social media platforms and find photographs,” Fullerton Police Department Sgt. Kathryn Hamel told ABC News of the suspect, Arturo Galvan.

“He would then collect the GPS coordinates from those photos,” Hamel said. “He would then place them onto a map, and drive to his victims’ locations.”

According to court records, Galvan, who appeared in court on Tuesday, is accused of stealing a quarter of a million dollars in electronics since last year.
