Rockford, Illinois stabbing suspect blamed 'laced' marijuana, authorities say

The suspect in a violent killing spree in Rockford, Illinois, partly blames the incident on marijuana he says was "laced" with an unknown drug, authorities say.

Christian Soto was charged on Thursday with 11 counts, including first-degree murder and attempted murder.

Four people were killed and seven injured in the 20-minute spree.

Darlene Weber, a mother who was attacked in her home, described the scene as "like a horror movie".
