A suspected serial killer is charged with murdering one woman in Northwest Indiana, and faces charges in the deaths of at least six more.
Police say Darren Vann killed 19-year-old Afrikka Hardy at a motel in Hammond on Friday night.
They say Hardy was a prostitute, who was found dead by the woman who arranged her meeting with Vann.
That woman provided Vann's number to police, who tracked him down in Gary.
Once Vann was in custody, he told police where to find the bodies of six more women. Three of the six bodies found in Gary have been identified.
Investigators say Vann may also be responsible for dozens of other murders in several states and Mexico, dating back 20 years.
Hammond police say Vann is trying to negotiate a deal with prosecutors.
He has been moved to the jail in Crown Point.
Meanwhile, more information is being revealed about Darren Vann and his past.
Indiana court records show Vann was arrested in 2004 after police say he threatened to kill a man over $7,000 dollars.
Also in 2004, the Suntimes reports after dousing himself and his then-girlfriend in gasoline, he threatened to set them on fire.
Court records show - in a deal with prosecutors - he pleaded guilty to misdemeanor residential entry and was sentenced to a year in jail and a year of probation.
In September 2005, Vann admitted violating his probation and was sentenced to another 90 days in jail.
Authorities called Vann intelligent, and say he is very well-read.
Authorities in Austin, Texas and Cherry Hill, North Carolina are looking into their cold cases to see if Vann can be linked to any of them.
Though he is a native of Indiana, Vann recently spent five years in a Texas prison for raping and attempting to strangle a woman. He was released last year.
Both the homicide cold case unit and missing persons unit posted a list of cases on the web, and are asking people to call a hotline if they have any information.
In cherry hill, north carolina are also checking their records. That's where Bann was arrested on unspecified charges in 1993.
Vann's brother has come forward and apologized to the victims' families.
A preliminary hearing is scheduled for Wednesday at 9 a.m. inside the jail complex.
