(Michigan City, IN) -  Michigan City police have upped the ante in an ongoing murder investigation.

There is now a $1,000 reward associated with Tuesday night's shooting death of Darius Mitchell on the city's southwest side.

Despite a large crowd reportedly at the scene of the crime, police have not come up with the evidence they need.  Friday night, Chief Dion Campbell took to Facebook offering a cash reward.
