PORTLAND -- A grand jury indicted the teen accused of killing missing 14-year-old Yashanee Vaughn on murder and manslaughter charges.
The charges against 16-year-old Parrish Bennette, Jr. were announced Friday morning. He was ordered to be held on no bail in a packed courtroom Friday.
Bennette faces one count of murder with a firearm and one count of manslaughter with a firearm. The state further alleged that while committing the crime, Bennette threatened Vaughn with the firearm.

Investigators said they believe Vaughn was killed by her boyfriend, Bennette, last month. He had been held in jail on manslaughter charges after a juvenile judge reduced the charge.
