The man who shot and killed a well-known pro life demonstrator outside of a school in Michigan has been charged with killing another man as well as plotting the demise of a third person.

Dawson Bell and Chris Christoff of the Detroit Free Press has the details:

Harlan Drake, 33, of Owosso, was arraigned this afternoon on two counts of first-degree murder, one count of using a gun in commission of a crime, and carrying a gun with the intent to commit a crime.

James Pouillon, 63, was shot multiple times at around 7:30 a.m. as he protested across from Owosso High School, police said.

About the same time, gravel company owner Mike Fuoss, 61, was found dead in his office at Fuoss Gravel in Owosso Township.

Drake was arrested at his home after a witness to Pouillon's shooting gave police the license plate number of the car from which the shots were seen fired.

The third charge was related to Drake's alleged intent to commit a third homicide, said the Shiawassee county prosecutor, Randy Colbry.

Colbry said authorities do not believe that the two homicides and the third plot were related, saying, "They stemmed from individual grievances Drake had with the victims."

Colbry said the grievances were not known in detail, but that the killing of Mr. Puillon was related to the latter's anti-abortion protest. But he said, "The defendant was offended by the manner of Mr. Puillon's message."
