(WAFB) - Law Street Media, a company launched in 2013, decided to take a deeper look into Craigslist to see how dangerous it really is. Since the arrest of Philip Markoff, aka the "Craigslist Killer" in 2009, the Craigslist website faced increased scrutiny.
The study by Law Street Media found 58 murderers and 45 murder victims connected to Craigslist postings since 2009. There are 22 murder cases still pending, according to the study. The oldest pending case is from 2012 and eight are from 2014.
Another group doing research on the same topic, Advanced Interactive Media Group LLC, says since 2007, there have been 86 killings in some way linked to Craigslist. Advanced Interactive Media Group has launched an initiative to encourage police stations to host Craigslist and other online transactions. The initiative is called Safe Trade Stations.
Law Street Media says Craigslist did not reply to multiple inquiries from them.
