Anyone can go online and find out where you live — even, perhaps, the alleged shooter of several Minnesota lawmakers.

When police found the car that is believed to belong to Vance Boelter, the man accused of assassinating Democratic Minnesota state representative Melissa Hortman and her husband and shooting a state senator and his wife in their homes, they found notebooks, according to a criminal complaint in the case.

In one notebook was a handwritten list of 11 common “people search” sites, which are data broker sites that people can use to easily look up home addresses and phone addresses for free or for small fees.

The sites written down in this notebook included TruePeopleSearch, Spokeo, Pipl, PeopleFinders, BeenVerified, Whitepages, TruthFinder, Intelius, Ownerly, US Search and PeopleLooker.

In total, authorities also found the handwritten names of 45 Minnesota state and federal officials listed in notebooks that are believed to be Boelter’s.
