PORTLAND The family of a Portland 14-year-old missing and presumed murdered was set to hold another vigil for Yashanee Vaughn Tuesday, as the search for her body continued one month since she disappeared.

Earlier this month, a grand jury decided there was enough evidence to indict 16-year-old Parrish Bennette, Jr. with the murder of Vaughn, his 14-year-old girlfriend. Police said Vaughn was killed in a house not far from Rocky Butte.

The vigil Tuesday was set for the lot across the street from Madison High School at 2700 NE 82nd Avenue at 7 p.m..

Detectives now think there were others that could also be involved in her disappearance and murder and have more information.

Now is the time for those people to come forward and cooperate with the investigation and help Yashanee's family reach some closure, said Sgt Pete Simpson, Public Information Officer.

Vaughn's grandmother, Reynelda Hayes told KGW Monday the family has strong hopes that fliers showing Yashanee posted all over town will compel someone to come forward with clues that will help police solve her case.

Fliers with detailed information about Vaughn were being distributed throughout the community.

Family members hope the information will generate tips to help detectives and prosecutors.
