Black serial killer: Police investigating the slayings of seven women whose bodies were found in northwest Indiana said that they believe it is the work of a serial killer, and that the suspect has indicated there could be more victims going back 20 years

The Lake County prosecutor's office have charged 43-year-old black male Darren Vann of Gary, Indiana, in the strangulation death of 19-year-old Afrikka Hardy. Her body was found at a Motel 6 in nearby Hammond. Gary officials were expected to charge Vann in the deaths of six more women, whose bodies were found recently. Hammond Police Chief John Doughty said at a news conference that Vann confessed to Hardy's slaying and gave police information that led to the other bodies in Gary, including three on the same block. Vann is a convicted sex offender in Texas, where he pleaded guilty in 2009 to raping a woman and was released from prison in July 2013.
