Four gang members accused of murdering an Atlanta business owner were back in court on Monday. Otis Ricks, Gerald Peterson, Christopher Penson and Demario Carman are charged with killing Vanessa Thrasher. She was gunned down last August at OT's Lounge in northwest Atlanta.
Authorities say she was supposed to testify in a 2011 murder that happened outside the bar.
Investigators found no link between the two shootings, but prosecutors have not ruled a connection.
