The suspect was shot by officers at least one time, authorities say.
The individual was taken to a local hospital and is currently listed in critical condition.
No other injuries were reported.
District Attorney John T. Adams is expected to hold a press conference this week to discuss the investigation.
Authorities say there is no longer any danger or threat to the community.
