Here is what was reported by GQ Magazine about their tumultuous relationship:

Vis GQ: After reading an article about the young Raider, Denise Matthews, a.k.a. Vanity, now a born-again Christian, arranged a meeting with Anthony. Three days later she proposed to him, and one month after they met, he made her his second wife. (He’d had a brief marriage to a young actress a few years earlier.) But this new marriage, too, quickly turned to dust, recalls Dwayne Simon, a friend of Anthony’s from that time. Dwayne remembers one uncomfortable team-family breakfast before a Raiders game when Denise said or did something that made Anthony furious. “He grabbed her by the arm, made her sit down,” says Dwayne, a producer with the L.A. Posse and Def Jam who arranged music for Raiders games. “She tried to get up, but he snatched her back down: ‘Get down!’ I was really scared for Vanity. I thought he was going to break her friggin’ arm.”

At the same time, Smith was telling one of his rich-white-businessman friends that he had helped Denise get a kidney. (Her body was hard hit from years of drug use before she swore off that life and turned to God.) What a good guy. What an angry one. Was one of those Anthonys more true than the other? Or had he just become a violent man who knew how to shine?

It’s a good thing Vanity got away from Anthony before things escalated to the point of no return.

After he and Vanity divorced, Anthony married his third and current wife, attorney Theresa White. Theresa had previously supported Anthony in his past trials, but in his most recent murder trials, there was no one in the courtroom for Anthony, except his defense attorney. The families and children of the murder victims were in the court in full effect though.

Friends and family of Anthony Smith reported that he’d changed a lot and had isolated most of them from his life and befriended gangsters instead.
Those three murders aren’t the only legal trials Anthony has seen. In 2003 he got into a heated argument with a female owner of a furniture store in Santa Monica, Ca. over money. Soon after the argument, the store was set on fire using homemade firebombs that were stuffed with a bunch of mail from Anthony’s home. It had his name and his address on it. Prosecutors just knew that case was a for sure win, but Anthony was tried twice for arson in the case and both times the jury deadlocked. Also, several of his friends, who were alleged gang members, sat in court every day of the trial and stared down the jury. It isn’t certain if that invoked any type of fear into the jurors though, or if they sincerely believed Anthony didn’t commit the arson.
Fast forward to today and Anthony Smith is now serving three life terms without the possibility of parole. His attorneys say they plan to appeal the decision.

After seeing the details of Anthony’s story and his dissent into self destruction, it’s very difficult not to to think about the movie, Concussion, that highlighted the often violent mental condition, CTE.
Maybe Anthony Smith just became a violent man on his own, or maybe he could be affected by CTE, like we’re now seeing with several other ex NFL players, who knows? The downfall is that there is no way to determine this, until after a player’s death. In the meantime, if he did those crimes, he deserves to do the time. We wish peace and comfort over the families of the victims.
