MCSO says the FBI has agreed to conduct toxicology testing at their lab in Quantico, Va. According to MCSO, the reason for sending it to the FBI's lab is because of the large range of testing they are requesting and because the FBI is "one of the foremost experts in the world when it comes to this type of testing."
According to MCSO, Austin Harrouff told deputies, “test me, you won’t find any drugs,” at the scene of the double homicide.
MCSO detectives continue to interview family, friends and potential witnesses to the killings.
MCSO also confirms that Harrouff did bite the male victim in the abdomen area.
