(Stillwater, MN)  —  The Stillwater community is mourning a teenager who died in a stabbing spree along the Apple River.  Seventeen-year-old Isaac Schuman was tubing with friends when a Prior Lake man allegedly stabbed him to death and injured four others.  A candlelight vigil was held last night in honor of the incoming high school senior.  Hundreds of people turned up, wearing Isaac’s favorite color of orange.  More than 40-thousand-dollars has been raised through a GoFundMe drive to help his family.
