Bodies of 7 women found +Follow

(CNN) -- An Indiana man told police he "messed up" by killing a woman in Hammond, then came clean, leading them to several more bodies in nearby Gary, Hammond Police Chief John Doughty said Monday.
Doughty stopped short of calling Darren Deon Vann a suspected serial killer, but left the possibility open if police are able to connect the convicted sex offender to any of the six women found in Gary over the weekend.
"If we directly attach him to it, we can make that assumption," he said, adding that Vann's statements lead authorities to believe there are "possible other victims." Some cases may date back 20 years, based on what Vann has told police, the chief said.
