Jan. 16, 2016 will mark 19 years since Ennis *, *Bill Cosby’s then-27-year-old son, was shot and killed by a man named Mikhail Markhasev in what law enforcement authorities in LA believe was an attempted robbery.

And while the Ukrainian immigrant has since confessed to the crime, he recently sent a letter to Radar Online in which he seemingly denies allegations made in an upcoming “tell-all” called Cosby’s Love Child, which claims the since-disgraced comedian, 78, had his own son killed to prevent Ennis from revealing that the Cosby Show star fathered a “love child” out of wedlock.

“Ennis’ only fault was being in the path of a wicked idiot like myself,” the seemingly remorseful criminal, 36, writes.

“The senseless tragedy of his untimely death and the sacred sorrow experienced by his family is something that I hope you will never have to experience, and yet it happens daily in the world.”

In his letter to Radar, he also expressed sympathy towards the elder Cosby, who has been accused of sexual assault by more than 50 women.
