Sam Randall (uncle/brother)
Dante Randall (cousin/nephew)
Odafin Tutuola (brother-in-law/uncle)
Darius is the product of the rape of Teresa Randall (who is Detective Odafin "Fin" Tutuola's ex-wife) and his grandfather. He is the half-brother of Ken Randall (who is the son of Fin and Fin's ex-wife and who unlike Darius was raised by his mother). Darius was raised as Ken's cousin but learned the truth from his grandma's last words on her deathbed. He wished his grandma had never told him and that she had instead taken that knowledge to her grave.
He has grown to hate his mother for not raising him and for threatening him when he was twelve. He also hates Fin and himself. He eventually rapes and murders a woman he believes to be a bad mother and kills her infant son with the help of his then girlfriend, to free him of having to live a bad life. He eventually committed various other crimes like burglary, assault, and trafficking narcotics.
He later confesses to Ken, who protects Darius by refusing to reveal his confession and later claiming the crime has a different culprit, inventing a bogus story to support this claim. Darius confesses to committing the crime and helps the police find the bodies. Darius knew that since he did not have a lawyer with him that all evidence found would be inadmissible at court. When the police find extra evidence, Darius does not accept any deals, despite his lawyer's advice. He says he wants his day in court and threatens to blackmail the SVU Detectives. (SVU: "Venom")
Darius makes good on these threats and with the help of a corrupt cop he exposes the bad things that the Detectives did (example Eliot Stabler sweeping his daughter's DUI under the rug). He is found not guilty at trial. Shortly after the trial he meets Ken and Fin who both promptly disown him for what he did to the victim and the good detectives. Fin believes that Darius will always be looking over his shoulder for Fin, but Fin says he won't bother with him, but knows Darius will always be in fear of that. (SVU: "Screwed")
