Face-eating frat boy Austin Harrouff is still in the hospital, still cannot speak, now has pneumonia, and according to his father, Dr Wade Harrouff, is getting worse by the day.

It’s been four weeks since the teen went berserk, attacked and killed a couple in their garage, and began eating the victim’s face.

His father recently went on Dr Phil, explaining that he believes his son drank poison before the attack – explaining his son’s burned throat and the ‘animal noises’ he is said to have made while fighting off several sheriff’s deputies on August 15.

‘He was very dehydrated and wanted to drink something,’ Dr Harrouff said.

Other new details came to light in the interview, such as this odd tidbit:

Dr Harrouff told host Dr Phil McGraw that his son had left a restaurant where they had been eating without explanation, walked to his mother’s house two miles away and tried to drink a bottle of cooking oil. She stopped him, but he poured it into a bowl with Parmesan cheese and ate it.

She then brought him back to the restaurant, at which point Dr Harrouff said he grabbed his son by the shirt and said, ‘What is wrong with you?’

He said the teen reared back and raised his fist, but Dr Harrouff’s girlfriend told him to stop, and the young man left.

Video from the restaurant shows the teen walking calmly out of the building around 45 minutes before Stevens and Mishcon were attacked. He apparently walked the four miles to their home.

Craving cooking oil and parmasan cheese?

Never heard THAT before.

From The Daily Mail:

Dr Harrouff said he first got a call from deputies about 2am, about five hours after the attack. He told Dr Phil his first thought was ‘he’s dead.’They told him they had found his son and he was relieved, but then two deputies arrived at his house and showed him a photo of his battered son taken after his arrest.They told him his son was in the hospital and that ‘he’s killed two people and eaten them,’ adding ‘that blood you see isn’t his own.’

He said he was stunned because that’s not something he could believe his son could do.

‘He’s always been the kindest, caring kid I’ve seen. He always wanted to help people. He was always great. I called him the “happy boy,”‘ he tearfully told Dr Phil.

‘When he wakes up, he’s not going to be able to believe this but he will deal with it. I want to talk to him because he will tell the story, even if he is guilty.’

Hospital blood tests showed no signs of methamphetamine, cocaine, heroin or other common drugs in Harrouff’s system. Detectives are awaiting tests for less common hallucinogenic drugs such as flakka or bath salts, which have been known to make people suddenly and irrationally violent. Martin County Sheriff Wayne Snyder has said Austin Harrouff will be charged with murder if he recovers.

Really: How long does it take to get the toxicology results for bath salts and Flakka?
