Memorial service held for slain teen

Silliman's parents first reported him missing Nov. 26. Wake County sheriff's investigators say four other Wake County teens killed him Nov. 30. Authorities identified his body on Dec. 4.

Silliman's favorite tree on the church's grounds gave the adventurous Boy Scout an idea. He talked to O'Neal about his plans after spotting the area on the satellite images of Google Earth.

After reaching the pinnacle of Boy Scouts, Silliman helped found a Sea Scouts group, which taught nautical skills.

While some friends say the 18-year-old had recently grown distant, O'Neal said he was simply a good-hearted person.

"Matt has always been energetic and creative, just a little different," O'Neal said.

"This makes absolutely no sense to me. But we're taught that God has purpose and he's working his purpose out,” O'Neal said.

O'Neal said the last thing he talked with Silliman about was placing a bench on his church gathering spot. The Scouts and the church's congregation plan to add the bench in Silliman's honor.

Last week, police arrested Allegra Rose Dahlquist, 17, Ryan Patrick Hare, 18, Aadil Shahid Khan, 17, and Drew Logan Shaw, 16, and charged them with Silliman's murder.

The four suspects were being held in the Wake County Jail. Their next court appearance is scheduled for Dec. 22.
