|Family|| Janice Whitlock (wife)|
Jeffrey Whitlock (adoptive son, deceased)
|Status||Imprisoned for life|
Mark and his wife Janice got two life-insurance policies taken out of Jeffrey, making him worth $750,000. Wanting to gain the money as soon as possible after becoming bankrupt from paying the $350 monthly premium, they hired the Revolutionary Aryan Warriors to murder their own adoptive son. Coincidentally, they hired Brannon Lee Redding to carry out the killing. However, their scheme was discovered by FBI Agent Dana Lewis, who alongside Detective Olivia Benson arrested the both of them. He was sent to prison for life along with his wife for first-degree murder for hire.
