If you're going to make shit up, at least get the correct charge. It would be either battery or simple battery, not assault.
Actually, in Texas assault and battery aren't separate charges
Texas Penal Code § 22.01, et seq. Statutory Definition of Assault A person commits an offense if the person:
Intentionally, knowingly, or recklessly causes bodily injury to another, including the person's spouse;
Intentionally or knowingly threatens another with imminent bodily injury, including the person's spouse; or
Intentionally or knowingly causes physical contact with another when the person knows or should reasonably believe that the other will regard the contact as offensive or provocative.
This is just going off memory from a law class I took a year ago, but I think the crime is elevated to aggravated assault if a weapon is used.
You're right that paddling isn't a crime, though. Certainly not one that justifies murder.
Honestly, I was going off of the Georgia and California definitions of assault and they were almost identical so I pretty much assumed that Texas would be similar. People still say assault too much when it isn't applicable though. ---
