SOUTHFIELD, Mich. (November 12, 2012)--Authorities say they still are unsure what led a 64-year-old man to open fire at officers inside a suburban Detroit police station.
Southfield, Mich., Police Chief Eric Hawkins told reporters Monday there is no apparent motive behind the shooting.
He said a preliminary investigation revealed that the gunman, Harold Joseph Collins, was in poor health.
Hawkins says Collins of Southfield was a military veteran.
Collins was killed during a gun battle with officers Sunday afternoon in the lobby of the department's headquarters building.
One officer was shot in the shoulder during the exchange.
Hawkins said the officer was in stable condition Monday.
Police say Collins first tried to shoot an officer behind bulletproof glass before other officers confronted him.
The Oakland County sheriff's office is investigating the shooting.
