Olivia traveled by herself to the apartment of Matthew and Ashley Schroder. When she arrived, CSU along with the ME's office were already checking the crime scene and collecting evidence. Olivia was pointed to the bedroom where the victims were. She proceeded to the bedroom and found Warner examining the bodies.
"What have you got for me, Melinda?" she asked.
"Same story I had with the Knabs," Warner replied. "Ashley was raped in the same three ways before being manually strangled to death. Matthew was sodomized before suffering massive internal bleeding. It has to be the same perps and there's no way it could be Dominic Knab since time of death was about three hours ago, and you had him in custody."
"Okay, thanks, Melinda," Olivia said.
When Olivia returned to the station, she met with Fin and briefed him on the events surrounding their case. They went to the interview room where Dominic was still sitting.
"Good news, Dominic," Olivia said as they entered. "We're not gonna finger you for your parents' murders. We have irrefutable evidence that places you at a bar at the time of their deaths. We also have three other victims to handle so we can't charge you for the murder."
"But before you get all excited about being let go, we're still arresting your sorry ass for assaulting me," Fin added, picking Dominic up and trying to lead him from the interview room to the holding area. Dominic tried to put up a fight before Fin continued. "Do you really wanna try and fight me? I can get you for a double assault if you keep trying to escape."
Dominic stopped resisted and let Fin escort him to a holding cell. While Dominic was being lead away, Olivia straightened up the interview room before heading to Captain Cragen's office.
"Captain, we now have five victims under our belt. We are going to have to work really hard to find something to get a suspect."
"Well, there's nothing more we can do tonight. Go home, Liv, and get some sleep. Warner will have results for us tomorrow," Cragen replied. Olivia nodded and headed home to her apartment.
The next day, Warner came into the squadroom to let the detectives hear her findings from the attacks, as well as those found from CSU.
"CSU didn't find any prints at the Knabs's home," she explained. "Nor was there any DNA at their home. However, I think you're killers are becoming cocky."
"How so?" asked Munch.
"CSU found two sets of prints in the home that didn't belong to either of the victims. One of the prints matched to a set found on the lamp post used to sodomize Matthew so they likely belong to the one who attacked him. I also found semen in the three places where Ashley was raped."
"Bastard let himself rest before he kept torturing her," Olivia said, disgusted.
"Exactly. Now, cause of death in all of the women has been manual strangulation," Warner continued. "Both of the men have been traumatized enough to cause internal bleeding, allowing for a slow but very painful death. There are definitely two perps, but I can't really figure out their relationship. Dr. Huang, what do you think?"
"The killers are obviously very close to each other," Huang explained. "They could be dating, married or may even be family members. I think the killers are one male and one female. I'm guessing the man rapes the women while the woman sodomizes the men enough to cause them to bleed out. They are very violent people with a passion for sexual deaths. They could find their own sex lives unappealing and take that out on other people together in order to let their relationship approve. Bottom line, the killers are very close to each other."
"Okay, we know the killers are close, but we don't know the connection between the victims," Cragen said.
"Well," Olivia said. "All of the victims were sexually assaulted before they died. Grace Bontz was home alone when she was attacked but the Knabs and the Shroders were together at the time. Grace had a boyfriend, but he was at work at the time of her death. It seems like the killers wanted to have both members of the relationships to kill so they chose to wait until both were together in the same room before they attacked." Olivia paused for a moment before continuing. "I don't understand the connection between them."
"I think I do," said a voice from behind all of them. Cragen, Warner, Huang, Munch, Casey, Fin and Olivia all turned around to face the speaker. When the saw who it was, they all let out gasps of shock. It was Elliot Stabler.
