EVERETT, Wash.: Memorial services have been set for the 15-year-old gunman and a victim of the school shooting in Washington state.

Meanwhile, officials say the investigation into the shooting Friday at Marysville-Pilchuck High School north of Seattle will be long and slow to ensure any information released is accurate.

The Daily Herald reports shooter Jaylen Fryberg will be buried Thursday after a traditional two-day funeral for the Tulalip tribal member.

The paper says the funeral for one of his victims, Zoe Galasso, is set for this weekend. No word on a service for the third victim, Gia Soriano.

Two wounded students, Andrew Fryberg and Shaylee Chuckulnaskit remain in critical condition. A third, Nate Hatch, is in satisfactory condition.

Snohomish County Prosecutor Mark Roe met with detectives Tuesday and said they need to be given time for a painstaking investigation.
