Nineteen-year-old Austin Harrouff is charged in the double homicide of married couple, Michelle Mishcon Stevens, 53, and John Stevens III, 59. The killings took place August 15, 2016 at the Stevens’ home near Jupiter, Florida. Harrouff is accused of stabbing the couple to death before sheriff’s deputies allege they found him using his teeth to tear the flesh off John Stevens’ face and abdomen. Harrouff also allegedly stabbed the Stevens' neighbor, Jeff Fisher, 47, who was injured, but survived the attack.

Following the attack, Harrouff was hospitalized for several weeks before being charged with two counts first-degree murder, and one of count attempted murder. Dr. Phil conducted an exclusive interview with the accused man via video chat just days before he was transferred to jail.

“It’s like waking up in a nightmare,” says Harrouff, in the opening moments of the interview. “I feel really bad about what happened. I can’t sleep at night.”

The former Florida State University athlete asserts he had weird dreams and heard voices both before the attack, and after he was hospitalized. “I wasn’t aware of what was happening to me,” he claims. “I didn’t know if it was reality or if it was a dream.” Harrouff says he didn’t know Michelle or John Stevens and denies knowing why the attack happened.

Initially, investigators said they suspected Harrouff was high on “Flakka,” a street drug and psychoactive stimulant that has been linked to other violent acts. Later, test results reportedly concluded he was not on that or any other hallucinogenic drug. Harrouff’s father, Dr. Wade Harrouff, claims his son began exhibiting the signs of mental illness about two weeks prior to the night of the killings.
