The Indianapolis police department is starting to use big data to respond to crime quicker, even predicting where it will happen.

On his first full day of work, Indianapolis Mayor Joe Hogsett rolled out his public safety strategy.

Indianapolis' new police chief says the past six months have been "extremely violent" as he prepares to put on the IMPD badge.

Troy Riggs will return to city government in January to be the chief of police under Mayor-elect Joe Hogsett.

Mayor Greg Ballard announced Wednesday that David Wantz, the vice president for government and university relations at U Indy, will serve as interim director of the Department of Public Safety.

Public Safety Director Troy Riggs says the number of Indianapolis homicides have declined 22 percent so far this year compared to the same period last year.

A new public safety director for Indianapolis will likely be announced later this week and the replacement is expected to be someone from outside of government.

If Indianapolis wants to continue to attract top officials to run government agencies, the outgoing public safety director warns they'll have to be paid more.
