From a murder allegedly sparked by an "unfriending", to people posting evidence of their mischief online, social media is playing a bigger role in catching criminals.
Andrew Marcum was arrested in Ohio in March of 2015 after turning himself in to authorities after a sheriff's department used Facebook to ask the suspect to "stop by".
Marcum was wanted on a variety of charges, including burglary and abduction.
The Butler County Sheriff's Office first put out an alert for Andrew Marcum on their Facebook page. Several people commented on the post, saying they could provide information about the 21-year-old.
Marcum even commented on the post himself, saying, "I ain't tripping half of them don't even know me."
The sheriff's office then responded to Marcum's post, saying, "If you could stop by the Sheriff's Office, that'd be great."
