UNDATED (WSAU) Federal prosecutors say they will not seek more charges against Scott Johnson, who was convicted of killing three teens in a rampage on the Wisconsin-Michigan border.

The 39-year-old Johnson was sentenced in a state court earlier this year to life in prison with no chance of parole. He molested a woman at a swimming hole west of Niagara last July – and then he returned the next day and shot at nine teens swimming in the Menominee River. A federal conviction might have given Johnson the death penalty – even though Wisconsin does not have capital punishment for state convictions.

Survivor Daniel Gordon said F-B-I investigators met with him and the victims’ families last week, and said there would be no federal charges. The U-S Attorney’s office made the decision public yesterday.
