History[]
When Stabler's investigation into his wife's murder led the squad to a warehouse where Rafiq was murdered, Stabler found a copy of his ID and ended up investigating Rafiq's death. Stabler then discovered that Angela was his mother and confided in her that Kathy was murdered, causing Angela to feel sorrow towards him. Stabler then discovered that Wheatley was his adoptive father and Manfredi Sinatra was his grandfather, causing Stabler to become suspicious about Sinatra's involvement in his wife's death.

After Bekher told Stabler that Angela was responsible for the death of his wife, Stabler arrested Angela for Kathy's murder. Angela confessed to Stabler that Wheatley manipulated her into believing that Stabler was responsible for the death of Rafiq and shot him during a police raid. Wheatley then asked her if she wanted Stabler to die and Angela claimed that she wanted Stabler to suffer like she did when she lost Rafiq. Angela insisted that they were all just words and she didn't mean for Kathy to die. Stabler then revealed that Rafiq was going behind Wheatley's back and creating his own version of Purple Magic, causing Wheatley to catch him in the act and shoot him in the act. After hearing this news, Angela agreed to help Stabler and Bell put Wheatley away. (OC: "I Got This Rat")
When Carisi took Wheatley to court for Kathy's murder, Carisi discovered that Wheatley had Kathy murdered because he didn't want Angela to find out that he murdered Rafiq. (SVU: "People Vs Richard Wheatley")
