Ryan Patrick Hare, 19, is charged with first-degree murder in the death of 18-year-old Matthew Silliman in December, 2008.
Police have implicated three other teens in the murder: Aadil Shaaid Kahn, 18, Allegra Rose Dahlquist, 19, and Drew Logan Shaw, 18.
Sheriff's investigators found Silliman's body on the bathroom floor of an empty mobile home near New Hill in southwestern Wake County on December 3, 2008. According to the medical examiner, the Eagle Scout was drugged and suffocated.
Prosecutors allege Hare masterminded the plot to kill Silliman because he was angry about a relationship between Silliman and Dahlquist - his girlfriend. They say Hare convinced Silliman that a hit man was after him and he needed to hide out at the mobile home.
Dahlquist took the stand for a second day Wednesday. She told the jury that she, Kahn, Shaw, and Hare went to the mobile home the day Silliman died. She said Hare hit Silliman in the head with a hammer, but Silliman was not knocked unconscious by the blow.
She said the group then told Silliman he had to die either by suicide or they would kill him. When Silliman asked how, Dahlquist said Hare told him it would be by suffocation.
Silliman told them he was afraid to die that way because he knew a friend who had died by suffocation. The group then gave him the option to overdose on horse tranquilizers.
She said Silliman began to mix the drugs with wine he was drinking.
At that point, Dahlquist testified she took Shaw home because his mother had told him he had to be home by a certain time.
When Dahlquist returned, she said Silliman appeared to be drunk and his conversation was rambling.
"He was talking about nothing," she said.
Dahlquist said that Silliman eventually passed out, and the three remaining teens carried him into a bedroom in the mobile home.
She said Silliman's hands started to move, so Hare told her to zip tie his hands, and then Hare zip tied his ankles. She said Kahn then put duct tape over Silliman's mouth.
The group then moved Silliman into a bathroom with no windows.
"So nobody would see if they walked by," she said.
Dahlquist said Silliman then began vomiting through the duct tape and then she and Hare put a bag over Silliman's head.
"Ryan handed me a zip tie and I put it on his neck but I couldn't get it on all the way," she testified.
She said Hare then tightened the zip tie further.
The prosecutor then asked Dahlquist why she did it.
"I wanted to get [Hare's] trust back and if I did it I would get it back more," she said through tears.
When asked whose idea it was to kill Silliman, Dahlquist responded: "Ryan's."
After the killing, Dahlquist said the group went out to eat.
She said Kahn made the comment that Silliman "wasn't a death fail anymore."
The following Monday, Dahlquist went to school as normal, but that her conscience bothered her.
"I thought that whenever somebody looked at me that they knew what happened," she testified.
Dahlquist testified as part of plea deal with prosecutors. While Hare is charged with first-degree murder, Dahlquist has pleaded guilty to conspiracy, attempted murder, and second-degree murder. She is to be sentenced after Hare's trial is over.
Dahlquist and Khan were classmates at Apex High School with Silliman at the time of his death while Shaw was a sophomore at Panther Creek High School. School officials have said Hare withdrew from Panther Creek earlier in 2008. All of the defendants, except Hare, were under 18 at the time of the alleged murder
Prosecution moves to revoke Kahn plea deal
Aadil Kahn also entered a into a plea agreement with prosecutors. But in court Monday, the prosecution entered a motion to revoke Kahn's plea agreement. In its motion, the prosecution said Kahn is no longer cooperating - citing a "lack of memory on events defendant had previously been able to recall, and inconsistent statements."
A hearing on the prosecution's motion has not yet been held.
