Authorities believe that Austin Harrouff, who is still in critical but stable condition at a local hospital, drank hazardous household chemicals moments before allegedly attacking John Stevens and Michelle Mishcon in their Florida home.
While the teen tested negative for common drugs like heroin and cocaine, officials are still testing to see if Harrouff was under the influence of bath salts or the synthetic drug flakka at the time he attacked the couple.
Investigators are still trying to figure out what caused Harrouff to become irrationally violent, and are unsure whether the attacker drank the chemicals to hurt himself intentionally.
One thing's for sure, when Harrouff is released from the hospital, he will be charged with multiple counts of first-degree murder.
According to reports out Sunday morning, Angelina Jolie's political ambitions with the United Nations may have caused a rift between her and Brad Pitt, at least based on a source "close to the couple."
TMZ is reporting that Jolie's dream had been to become a top official with the UN -- which makes sense, considering all the charity work and traveling to developing nations that she does -- but that didn't fly at home with Brad.
