School district bans sites, but would "Slenderman" have raised red flags before stabbing?

WAUKESHA (WITI) -- New developments -- one day after two 12-year-old girls were charged as adults, accused of plotting their friend's murder for months, and attempting to kill her in a Waueska park this weekend.

12-year-old Morgan Geyser and 12-year-old Anissa Weier each face one count of attempted first degree intentional homicide as party to a crime — and each faces 60 years in prison.

The criminal complaint in the case says on Saturday, May 31st, a citizen called Waukesha police to report a stabbing — after locating a 12-year-old girl suffering stab wounds on the sidewalk in the area of Rivera Drive and Big Bend Road.

The complaint says the girl told the man: “Help me, I’ve been stabbed.”

The man called 911 and tried to apply pressure to her wounds — and stayed until the Fire Department arrived.

On Tuesday, June 3rd -- for the first time, we're hearing that man's 911 call.
