Diego Diaz was a member of Miguel Lopez's gang and sex trafficking ring. He eventually abducted and murdered Pamela Stone.
History[]
In the aftermath of Lourdes Vega's siege, ADA Stone planned on locking Miguel up for his crimes. Diego met Peter at a bar, revealing he is the brother of Jorge Diaz (the man that Vega killed) and he threatened Stone to drop the case on Vega to have her deported and face his revenge or that he will hurt his sister, angering and frightening Peter who had a protection detail guard her. Because Peter did not back down, he abducted Pamela from her psychiatric ward, killing the guards, completely trashing the place, and threatening to harm several staff and patients.
Eventually, the Special Victims Unit found Diego and Pamela, triggering a standoff between the police and Diego. When Pamela tried to run to her brother, Diego shot her several times and tried to escape but was soon gunned down by ESU and SVU detectives, while Pamela died from her wounds.
