Just did some research on this and yes, it's possible. I still think steroid use and/or something else could be Involved but here's what I found in regards to your question:
The "superhuman strength" can come from the adrenaline and endorphins that are released in response to other factors during the psychotic episode, which doesn't have to be drug induced, it can just be from problems with the individuals brain Chemistry that get to a point of complete overload (it's more complicated than that but it is different for each diagnosis), so the adrenaline and endorphins can make the person move faster than they normally would and can cause their muscles to be able to lift more than normal just from the adrenaline and endorphins, but another aspect of this that keeps those experiencing this fighting and not being fazed by tazers or dog bites is the concept that the person is insensitive to pain during the psychotic episode, the technical term for this is hypoalgesia.

In terms of the cannibalistic aspect of this crime, I found one report that speaks about three types of biting in killers, but didn't specify whether the people studied were on drugs or not. It does mention that biting someone while killing them or after is "wild, sadistic, and animalistic." The three types they identified are: sadistic biting, anger-impulsive biters, and ego-cannibalistic biters. The ego-cannibalistic biter bites "in an attempt to satisfy ego demands by annihilating, consuming, and absorbing life essences from the victim."

Also, psychomotor agitation is really common in people experiencing a mental health crisis and biting is one example of how it can manifest in more extreme cases.
So yea, that prob wasn't helpful but while we wait for more info I thought I would share.
Wrong! Wonderfully helpful!! sadistic biting, anger-impulsive biters, and ego-cannibalistic biters. Helped me a lot TY!
Just learned that I was involved in anger-impusvive in the hospital setting, and was trying to say (ha did not know that!) that IMO he was not an ego cannibaliistic biter, never knew about a sadistic characterization and IMO that fits!!
A poster a while back reminded me that dad was a dentist. Chills. At that point the truth about the father and the shirt collar had not been revealed.
He and his father were obviously conflicted, or did not really know or understand each other. Felt that way in the boating video too - no interaction. When he was sitting near his father on the back of the boat while dad was barking orders about how they were gonna relocate the anchor- the dad was ignoring him . Just sit there and shut up. Act like your interested in "the right" way to do it- when you could really care less.
How that paragraph emerged (!) is on his FB/Twitter not sure which one- there are big teeth on it. At that time it just sturck me as his dads a dentist. But we know more now. With just learning about sadistic biter category the tone of big teeth takes on a different meaning. And then all this ran through my head:
We now know it (the giant teeth on Twitterr or Fb) certainly is not a "tribute" to daddy. Biting is mean and full of hate when humans do it to one another. Was this a release of his hate for his father. Kinda like wonder if he had been "fantasing" about biting/huring/killing his father recently.
It strikes me as intense inner torment. He so wanted to be able to control this urge to strike back at his father .
Wildy ironic that the day of the attack his themes were dad
you are in danger and
I will protect you.
He did it to the male in the garage . I posted it earlier but their was a chilling lyric he wrote about biting in a rage.
Was dad in danger from HIS demons? Evidnece says there was blood on the sidewalk. Was he attempting to stop "himself" from doing (by stabbing himself) what the voices were telling him to do, by using his switchblade againist himself? (He liked showing his body, there would be signs of self mutlating behavior if there was a history of such behavior.)
And, an hour so before the attack ,dad attempts to choke him ("pulling at his shirt at his neck is a nice way of saying it IMO! Putting your hands around someones shirt collar is trying to choke someone -- lets be real !!! Trigger pulled - intensly enough to where he felt he had better get away from his father, and calmly exits.
But mom takes him back............
Hours later he is found bear hugged, around a male , in a garage, in house that might look like where his dad his lives, one block off from dads house, savagly biting a male?
If one thinks about it , in the very poor way I wrote this - it truly is chilling- was he sadistically killing his father that night. He stabbed the female (mother?) in the garage.
However, his slaughter of the male was much more intense, up close, personal , savage and rage filled. He did not bite the woman. LE conclusions regaring his streghth, might it actually have been-- so not wanting to
stop biting the male (his dad?)
He was emmersed in the act. If one also visulaizes the way LE described what they were seeing, ("wrapped around" the victim- it can alternavily, give one an image of a hug ----- talk about conflicted emotions/thoughts).........................intense huh
Warning Graphic: Repulsive thought, but they are sick when responding to stimuli -- might Wesson oil be preparation (oiling teeth/mouth)
Pause there a minute.
......... In a profoundly disturbing manner, that makes some sense, as it relates to Wesson drinking oil , in light of what transpired shorly afterwards, - does it not? I wont be able to sleep tonight.
All just scary speculation - the power of an ill mind huh?
PS: not a fan of Freud.............just sayin'....................
Reminds me much of Omar/Pulse/his father relationship/killing gays/ etc
